What DOES cause an economy to collapse is taking more and more from one sector of society and giving that to another not because they merit it or were denied any benefit from society, but purely because they have less and will keep voting in people who will pay them for being poor.
This is why I support a flat tax that is uniform across the board. Any change that benefits one group benefits all. Any change that hurts one group hurts all. And THAT, coupled with an iron clad law that Congress is prohibited from using tax revenues to dispense charity or benevolence of any sort that benefits some but not all, I believe would solve a very large lion's share of both our economic and social problems in this country.
Again, the USA is not Europe. All European countries are far more like one of our states or even one of our larger cities or counties than they are like the USA. The USA was founded and designed on an entirely different principle than the European model and it has been a success. I do not wish to revert to the European model.I use Europe as my example, their income tax is even more progressive as ours, but the people do not vote in large enough numbers to support any radical leftism that you are fearing.
I have not said that progressive income taxes have ever or will destroy an economy. I think if you think that is what I said or implied, you should look more closely at what I have actually said.Sure, it is more leftist policies then you like, (and my post here has nothing to do with if the US should be more or less like Europe) but you can't say that progressive income taxes will destroy an economy, because Europe is doing fine enough.
