In short the rich folk have the country over a barrel due to FPTP-voting and a lack of campaign financing subsidies. This scheme was designed by ancient wealthy romans for the benefit of ancient wealthy romans and it's not a coincidence this form of democracy is the one America seeks to deliver upon the rest of the world.
Literally it's called "the great experiment" because it's failed before and will fail again if not allowed to evolve and advance into a form with better representation and where wealth doesn't dictate everything happening.
The greatest driver of violence, crime and corruption is wealth-inequality, it's no coincidence unions and such worse are branded as communism and criminal behavior by the plutocrats running the country, unite and demand change!
Quirk of a polarized political system thanks to FPTP-voting. Sooner or later even the lamest, most basic stuff suddenly turns political and "controversial" while billionaires laugh all the way to the bank. It's by design and what happens when groups of individuals are allowed to hoard obscene wealth and use it to rule the masses.
