Thing is, you don’t have to own it to control it. A few regulations can go a long way towards keeping the capitalists whose only concern is the bottom line, from doing everything they can think of to extend that bottom line. Someone has to look out for the environment, and the people that create and use the things capitalists own for profit.
The problem we face today is that we don’t control our government, so we have lost the regulations we put in place through our government that protect us from the profiteers. This is all you need to remember when the words Socialism and Communism start flying around.
Well, that and elect representatives that aren’t sympathetic or beholding to the profiteers.
