You're right that the wealthy do pay a lot of taxes
but
Dave is also right that the wealthy and corps use all the loopholes and "food stamps" they can get their hands on, too
Just a general note, by the way.. Dollar General, in the OP, is actually MEANT for lower income shoppers. If one wants a higher class of shoppers around you, then there are OTHER stores to go to. Things may cost more, but nothin's free in life.
You get what you pay for.
If I walk into a Family Dollar or a Dollar General, then I already know what I'm walking into and don't expect different.
Cog is like expecting caviar and arugula, at the Piggly Wiggly.

Or, like going into a dive bar, ordering champagne and complaining the bikers are "uncouth." It's a dive bar, that's what it is. If you choose to slum it, then you just gotta roll with it man. This is Dollar General, this is what it is.
P.S. Cog would have more of a gripe if it were a mixed-class store, or higher end.
Personally, I live in an income-mixed area. I've got a Family Dollar close to me. It's NASTY. It's just so gross. I get depressed just walking into that thing, it's got literally homeless people shopping there. Yet.. it's close.. it's actually not even the cheapest though, sometimes poor stores COST MORE.
So..
What I wind up doing, more often is driving OUT of my way to shop at a nicer store. And then, some places like a "save a lot," I'd never STEP FOOT into that.
And then, we've got a chain of very NICE grocery stores down here and if you go into that one you can be sure of a great experience -- but your darn bill will be at least 1/3 more, if not 50% higher. Or, there's whole foods and trader joe's etc. There's options in most places, you get what you pay for, Dollar Generals are just a lower level.
