Since I the left wing is in favor of people's rights it should be good, but most if not all countries that have left wing governments (such as most of latin america) are in a poor state while countries with right wing governments are in a better state in comparison despite the fact that people hate the right wing and im now confused.
That's a tough question without simple answers. You also make asdumptions that i think are already corrected by now. Nonetheless, I'm going to give a birds eye perspective on things
See... The whole 'left' and 'right' are a simplified way of looking at the spectrum of society
There are three or four... Pillars is perhaps the best word
* government, represented by politicians.
* the people, represented by unions and interest groups
*corporations, represented by ceo's and lobbyists
(* middle class, represented by... Small Business owners perhaps?)
No society can live without these, but the strength differs on many areas. Postal services can't be both privatized and nationalized, for example. And though each have strengths and weaknesses, this is all a potential.
Communism is all about a strong government at the cost of the others. Corruption is it's main potential weakness.
Socialism is power to the people. Unions, however, have no share in profits, so petty Corruption and/or bureaucracy is common.
Liberalism is about smaller companies. From my view, they tend to erode the government, but I'm the last familiar with this one.
Capitalism in this context is liberalism in it's extreme. It aims to privatise everything. It's the most efficient (more money=good), but has about as much personal freedom as Communism.
Good and bad aren't good measures to weigh these powers. Government taxes people to find projects. But how much is 'good'? Should it fund libraries? Subsidize hospital? Pay unemployed people?
One of the things that big me about Trump is that he spreads his ignorant knowledge of politics. Democrats are hardly pro union, met alone that they want to nationalise sectors. If that's "extreme left", it'd be funny to see how he could describe Sanders's ideas.
The sad reality is that corporate media (traditional Capitalism) ridicules any slight direction of democrats to do something liberal, and as such lean more Capitalism (the monopolisation of Google isn't something they'd tackle, for example).
And what's often mocked as 'Orange man bad' misses the absurdity of the situation: there'll be someone on top of the government who doesn't realize its role and just wants to get rid of it because it doesn't make a profit.
There are many examples of his first term, but I'll give this one: nuclear waste control. It's an Offspring from the tests of world War 2.it's a cost that, if not payed, would cost more in healthcare. But Trump wanted to get rid of it, and it was only due to diligent clerics that the cost cutting didn't materialise... Then.
