I think you have confused our constitutional system, a system in which capitalism thrives, with capitalism itself.
Papists (and other mystics) take note: our economic decline -- including the economic decline of the working and middle classes -- began in the 1930's, just when we began to impose the very "processes" and "structures" that the pope is calling for more of. The poor have been able to live off of the depreciation of a wealthy nation for 80 years, but the time is now upon us when the very plans, structures, and processes that the pope thinks are such grand ideas, instituted during America's "progressive" era, will mean widespread misery for the poor.
A broke country doesn't take care of the indigent very well.
It goes without saying that he'll never realize what caused the misery, any more than will you or his other blind followers.
