The tax code should not be "progressive" at all,
You stated that the current tax code is bad, in that it leads to "stratification of wealth and social breakdown". The current tax system, when you count all the taxes people pay, is, on balance, relatively flat. Therefore, you're arguing against flat taxation.
Your idea to tax every individual at the same rate regardless of their income is the definition of a flat tax. (Actually, since one needs disposable income to contribute it to charity, your plan is somewhat regressive.)
You're arguing both for and against flat taxation. I can only conclude that you're rather confused.
stop with the Marxist based taxation rhetoric already!
The word "Marxist" has a specific meaning. Given that the intellectual history of progressive taxation can be traced back to Adam Smith, you're apparently using it to mean "things I don't like".
Unless you're willing to put forth the claim that the vast majority of economists are closet Marxists and that every democratic nation in the world is run by secret Marxist cabals, a progressive income tax is not a Marxist idea.
The U.S. government needs to be restricted, by Constitutional amendment, to stop spending more than it is making *and* to not spend more than 10 percent or so of the GDP. Those two things are necessary and vital to the survivability of this country.
Staving off a second Great Depression was also necessary and vital to the survivability of this country. Massive tax cuts for the already-wealthy and optional military adventures abroad, on the other hand, were not. If you have a history of arguing against unaffordable tax cuts and spending increases on weapons, please do share it with me. I have a hard time believing that this isn't just the annual crop of people whining about how they don't like to pay taxes.
They are either incompetent or the financial ruin is something they are directly causing and planning to capitalize on. Which is it, smart guy?
Honestly? I think the folks who got us into this mess in the first place circa 2000 (not that the current folks seem terribly inclined to roll back the wars and tax cuts) did so out of a combination of naked self-interest and believing their own nonsense about the Laffer Curve or whatever bit of gimcrackery justified their neofeudalistic ambitions.
Of course, the game is rigged so that, without massive spending cuts (I don't think you've thought through your proposal to have millions of impoverished old people descend on their adult children for a place to live) or--perish the thought!--tax increases, for instance, to the insanely confiscatory levels we suffered through in the horrible dark days of the 1950s, we're stuck here.
I mentioned Grover Norquist before, but since you seem to have gaps in your understanding, I'll summarize his ideology, which has been shared by many of the movers and shakers on the right over the last few decades: You want to cut services, but people seem to enjoy them. So, you cut taxes and spend money, preferably on things that don't really benefit anyone (such as totally optional wars with no defined endpoint), in order to run up a gigantic deficit. Eventually, the government must spend every bit of money it can to service the resultant debt, and will, in the end, have no choice but to cut services.
So, to the extent that any one ideological group is responsible for this little pickle, I blame those guys.
