$this->bbcode_second_pass_quote('Tyler_JC', 'H')ere's the problem:

1950s/1960s America had a much stronger long run growth potential than the America of today.
It didn't take long run growth to significantly reduce the national debt/capita in the past. From ~1950 to ~1960, economic growth was only at ~2+%/year on average, very close to what we've seen since the 1990s, and national debt dropped by about
$15,000 per person.
$this->bbcode_second_pass_quote('Tyler_JC', 'I')n 1945 America had 132 million people. In the next 20 years, we added 60 million people for an increase of nearly 46%. Even if we hadn't done anything, the debt per capita level would have dropped substantially.
In 2010, we'll have ~306 million people and we expect to add another 59 million over the next 20 years. As a percentage, that's only 19%. The population growth rate only drops off from there. The debt levels per capita won't drop nearly as quickly as they did during the population boom years of the post war period.
If we have $10,000 in debt per person, a population increase of 46% decreases the per capita debt to only $6849/person.
If the population increase is only 19%, the per capita debt level only drops to $8403/person.
The real federal debt level is around $40,000/person.
Moreover, the US is a much more mature economy now than it was in the 1950s/1960s.
5% growth like we experienced in the 1960s just isn't possible anymore.
China can get double digit GDP growth rates because the country is so poor and has so many underutilized resources (labor, capital). Once the country becomes more wealthy, it's growth rate will fall.
If we hadn't done anything to change the per capita spending then debt would have stayed the same. What you seem to be stating is that if we drop real spending then debt will decline as population grows, but that's true regardless of whether or not we keep normal spending the same and increase population or cut normal spending proportionally to some lower population growth rate. For that matter, 5% economic growth in the 60s wasn't all peaches and cream when it was followed up by relatively poor economic growth in the 1970s. While current economic growth figures aren't as high as they were in the past, they also don't seem to be extreme. Recessions may be as common but they aren't as likely to be a 5% growth rate moving to a -3% growth rate over a couple years as opposed to the much smaller moves we've seen during recent recessions.
