Using your definition, any form of taxation is "forced redistribution", since 100% of respondents to the poll agree the disabled should be provided for, do you suppose if it was voluntary, it would be taken care of? If so, why were social relief programs ever created in the first place?
If people would voluntarily provide for the things social relief programs provide for anyway, why do such programs exist? Why did the great depression launch a national campaign that earned FDR 3 terms as president? Why were labor unions so successful in the '30's & '40's?
"Forced redistribution" is certainly happening today in that multinational corporations are redistributing the burden of picking up the slack their employees face paying the bills to the American taxpayer, and I know you already agreed with my earlier post about this, so I'm not placing the blame on those that acknowledge it, just pointing it out. It definitely exists, but it's in the exact opposite direction as previously stated, the wealthy are making the poor pay instead of the poor making the wealthy pay (for their own goddamn product/service).
Crony capitalism shows us that it excels with less regulation, free market capitalism requires regulation, and regulation is not the same as force, it's reining in the concentration of power that is inevitable in a capitalistic society. Men with unlimited power through wealth accumulation have the ability to change the game in favor of their financial and economic interests at the American peoples expense, eg. the bank bailouts. Regulation is not slavery, it's the way we keep capitalism a free market.
