We could well fall into a re-run of the great depression, but it won't be caused by futures trading. Here's probably more than you want to know about futures.
Oil, like all commodities, is traded globally on a number of exchanges. There's a "spot" market for oil that has nearly immediate delivery - this isn't any different (except for scale) to you pulling up to the gas station and taking immediate delivery of gasoline, paying today's price.
That's not the whole story, though. Commodities have long value chains, ranging from people who find/grow/mine/whatever the raw product all the way through finishers/refiners/whatever down to, well, us the consumers. Because of this, people involved in these businesses often want to arrange to buy (or sell) a product that they know they'll need (or produce) at some point in the future. Whether it's oil or oranges, a lot of people want to be sure that someone will take something they're pumping/growing today at a known price, while others want to ensure that some input they need (refiner needs to know where his oil's coming from next month, orange juice company needs to know where his oranges are coming from) will be there, and at a known price.
Futures markets enables people to buy and sell contracts to deliver or receive goods at later points in time. Generally, there are contracts on each that come due monthly, and are traded out years into the future. You can look at the prices of contracts for oil going out 2 years and get a sense for where the traders collectively think the market's headed. Don't kid yourself that you know more than they do because you're a PO'er, those professional traders are sharp and they'll skin you alive.
The existence of the futures markets means that even people without any interest in the underlying commodity can buy or sell contracts for it. People have been piling into these markets over the past few years, riding the boom in commodity prices. Indeed, it's likely that much of the trading activity in, say, oil, is done by investors basically betting against each other. There are likely many more contracts outstanding than there are units of the commodity actually being delivered through the system. Obviously if you've sold a futures contract (shorted it) but you don't have the goods, you're going to have to buy it back before the contract deadline, or you'll be stuck having to deliver the goods that you don't have.
Now, a lot of oil and other commodities change hands completely outside of this system, but the system still serves a function - it sets the market price on which other deals are based. Even if you (a refiner) are making a deal for oil from a producer for oil at regular intervals over the next 5 years, how are you going to agree on a price? Answer: you are going to look at the futures prices and then haggle based on that information.
A lot of people think futures trading is the spawn of the devil, and I don't really understand that. Markets are efficient, at least at price-setting. I wish everything I bought had a price established by a completely open, public market. Instead, you and I get ripped off every day because of inefficiencies and information-hiding built into most other pricing processes. (The internet is changing that, though, e.g. prices on high-tech goods.)
Some dangers in the futures market:
You don't have to put up all the money to buy a futures contract, you just have to put a down payment. This is reasonable, after all you don't have the goods yet. Oil is traded in 1000 barrel units, but you don't have to plump down $70k to buy a contract for, say, June. As little as $4k might do the trick. Naturally, if the price heads south, you're still on the hook for the full $70k. If the price drops to, say, $60 / barrel, you're down $10k but you only put up $4k, so your broker will demand that you pony up the $10k, or he'll sell out your position. Actually the broker would do that before you went "negative" in the position - the $4k is supposed to be enough to ride out any minor fluctuations so he's not calling you every day for more money.
You can buy options on futures contracts. The option to buy doesn't obligate you to buy, but it guarantees you a price in the future. This is a so-called "derivative" investment, because it derives it's value from the underlying asset. Naturally, you pay for the privilege - I'm not selling you the option to buy oil at even $70 / barrel at some point in the future unless I get some cash from you, cash that you won't get back from me. That cash is my compensation for taking the risk that oil could head north to $80 / barrel and I'll be stuck selling it to you at $70. A lot of people have been concerned that derivatives are the spawn of the spawn of the devil.
The problem in both of the above cases is leverage, and I think that's where your husband is drawing the analogy to the great stock market crash. Buying things with just a few percent down and the rest borrowed money means that a small move in the wrong direction can wipe out an investment. Stocks, which can be bought on margin, were the cause back in 1929; today, margin requirements are 50%, meaning a stock has to drop in half before you're wiped out. Commodities don't need anywhere near that much of an adverse move to wipe you out.
I have a commodities trading account, but I haven't used it in years. Anyone can do it, but there are financial requirements you have to meet before getting approved. Everyone in the investment community knows about the risks above, so they want to make sure you have sufficient assets to back up a commodities position (especially a short position, where you sell a contract without owning the underlying goods). Put it another way, the loan sharks want to know what stuff you have that they can take if you don't pay up. So, not as dangerous as it appears.
Most commodities trading is of course done by pros. A lot of people invest in "hedge funds" and these hedge funds have been big players in the recent commodities run-up. They have deep pockets too, but unlike me, they have all sorts of ways to get around the leverage rules. You may remember hearing about the infamous failure of a company called Long Term Capital Management back in the late 90s. This was a fund run by financial wizards who thought they couldn't lose, had carefully constructed computer models, etc., etc. They were like gamblers laying off action against different markets all designed to make money on the spread. Problem was, they didn't count on some of the other players to just flat-out default. It's like you won big in a poker game only when you go to collect, you find that the guy you beat says his wife left him and he can't pay. Because of leverage, the whole thing fell like a house of cards with just a small adverse move in one area.
Nothing's changed recently except that Wall Street has made a new Exchange-Traded Fund (ETF) available to the mass market so that they, too, can invest in commodities, without being a hedge fund manager or a well-heeled investor. ETFs work just like stocks, you buy and sell shares in them, and you have to put up all the money (well, OK, half the money). What I do not know is what assets these new ETFs have. If they are just buying outright commodities futures contracts (i.e. putting the whole $70k into an oil contract), then it doesn't really seem so bad. In fact, it's probably the only way the little guy gets a chance at direct participation in oil's upside (before, all he or she could do is put money into oil company stocks or oil mutual funds). It's possible that the ETFs use leverage, though. Then, like, yikes.
