I think the point was always to collect revenue from the rich and give it to the poorest people you could find
I'm not sure who should be laughing at whom. you're right about Keynesianism representing redistribution of wealth from the few to the many, but I also think Keynes was probably smart enough to know that if you take all the money from the rich and give it to the poor, that in a few years the former rich would become rich again and the former poor would figure out a way to lose it. That's just the social reality, and I don't think Keynes had any misgivings about it.
No, no, that was Keynes' intention - he did not think that high tax rates or redistributive programs would upend society, but precisely the opposite. His intention was to make capitalism work better in general and particularly for those who had previously suffered from it, to make it more popular and stable in order to preserve the position of the upper or owning class.
If anything we need to go back to more Keynesian economic policies. Our current policies are outright plutocratic and slowly inching toward that as we speak. Karl ROve has been selling these as "pro-family" where in esscence they end up destroying people. A prime example of this is the Child Tax Credit. It is a statistical fact that children from larger families perform worse in school, are more likely to join the military, and utlimately are economically worse off. The Child Tax Credit inadvertently encourages such behavior. There are so many things in the tax code I can go on and on about, but this is just one example. There are so many subtle loopholes the GOP puts through to eventually make our country like a Latin American plutocracy.
