Preditory capitalism does nothing for society in total. The best societies for the average citizen are a fine balance between capitalism and socialism. as in the North Atlantic countries or even Canada.

Non predatory capitalism doesn't drive its citizens into homelessness, as our current out of wack system is presently all about.

Insurance companies, hospital's and pharmaceutical companies are free to ripoff folks at will. It's not like that in other advanced nations where companies are expected to have a positive social purpose as well as a profit motive.

Just remember how it worked in our own country between, say, 1950 and 1975--the years of a booming middle class, It can be done again if only you can stop corporations from buying up the government GOP style.
