The problem is some of the "capitalist" as they call them have grown so large and powerful they're able to control and influence large sums of wealth, be it multinational corporations or corrupt international and domestic bank kingpins. All this wealth, power and control has allowed them to "game" and control the system.
This is one of the reasons why so many who still have jobs find themselves poor and in decline, with many of which are unable to even afford the basics, such as a home, even on two incomes. They work harder for less and less.
And there is no debate here. Simply look at middle America and the millions struggling and losing. All this while those few controlling the money become even wealthier and wealthier. So corrupt they now send out spokespeople to warn even their Social Security pittance which had been confiscated from them, will have to be cut or eliminated.
This is not going away as the vast distance between those few super mega wealthy at the top and the rest of middle America deepens.
that's NOT free-market "capitalism" - that's statism/fascism/crony-capitalism - whatever you want to call it. Its an iron rule - the larger the state is, the larger the amount of gaming the system, insider dealing, lobbying and outright corruption. In the USA, or financial system in particular has gone to the dark side. Banks are now political entities, bailed out by the Federal Reserve and US Government with your taxes, your savings and zero interest rates penalizing the middle class and savers.
