Because there is no party available to elect, who care for the workers/people.
You have a system that is designed to take money from the poor and lower class and give it to the rich. You don't have proper workers rights, spend about twice the amount for healthcare compared to an European person and get substantially less out of it. People work more than 40h/week in more than one job and can't make ends meet... There are vast rural parts that look more like a third world country. Everything is made for commerce and nobody cares for LGBT people or women unless there's some money or publicity in it.
And you have about 2 parties who both participate and stand for that scheme.
I agree. In my opinion there are two huge dominating factors.
First is the almost ubiquitous winner-takes-all election structure in the US, leading to the two party system. There is, bar none, no fair competition in US government at a level high enough to matter.
Second, the lack of term limits allows certain people in certain positions to perpetuate momentum. In part this happens by hand picking successors through brute-force out funding the competition (in part due to the economic disparity that others in this thread have mentioned).
Sure. Also silly tactics like Gerrymandering need to stop.
I'm not sure if these are the most pressing topics.
I think for one lobbyism needs to go for good. It's deeply undemocratic to give people money and then they'll pass your laws. And not the ones that'd benefit the people who elected them.
Maybe the members of the senate should be exchanged. Seems to me they're playing kindergarten games all day, blocking everything instead of doing their job.
And media is a big part if a democracy. And the media situation in the US seems beyond bad. People need actual information to make good decisions who to elect. Not a show filled with emotion where two old men compete against each orher like in a staged wrestling match.
And you need more parties. And they need to get like 10-15% of the votes. For example a party addressing the young people who complain that they never can afford to buy a house like their parents were still able to buy. A party catering to the people who don't live in the big cities. The farmers and rural people with different needs. A party who stands for the lower class people, the workers. Maybe something green, repairing the power grid in Texas and adding some more solar in the sunny south to the oil.
