The heart of the issue, imho at least, is that, regardless of what style of government is in place, society is ALWAYS going to have the same stupid problems... poverty, racism, health care, war, (insert favorite social issue here), etc., etc.
These are not problems related to government, they are problems related to the "human condition". They have been in existence throughout our history, and it's been proven over and over again that no governmental system or program will ever be able to erradicate them.
Unfortunately, that never seems to stop people from thinking otherwise... as the grass is always greener. So, no matter what system is in place, or how well it might actually be working, there are always going to be those who think if we change it, things will get "better".
In terms of modern day U.S. politics... well, in the 50's, people used to get deported for admitting to being communists or socialists, now there are representatives in Congress who freely admit to being socialists... so... you're guess is as good as mine, lol.
