Well I was about to say we are probably going to have another Cold War, except with China. I don't know about the brink of nuclear war though. Rights have advanced for people. The issue is with lack of regulations, not capitalism itself. Some companies are not only paying less than they should in taxes but actually getting taxes paid back to them. I wouldn't want to go full the other direction either though since a socialized healthcare system would likely be horribly mismanaged by the government, like a lot of the things they are aleady in charge of. You risk losing your rights and freedoms under socialism as well.
