There is an existential undercurrent in this country about the encroachment of corporations onto every aspect of our lives, because they have reliable paid-for partnerships with people who are supposed to represent the will of the people they were elected represent. Through this state-private partnership, power players at the top have bought themselves unfair advantages over the rest of Americans, including deadly advantages such as being able to over-charge for mediocre health care that many can't afford.
This is an existential threat that destroys even black people, who are being persecuted by police (corporate enforcers?), who are all too comfortable feeding private/public prisons, where lo and behold, corporations have a den of free slave labor for their wares... in 2017. It's not surprising to find paid-for legislators who could give three fucks about black people, yet happily sign legislation to facilitate all of this.
Considering so many aspects of our lives suck because our government promotes monopolies/oligopolies versus promoting more competition, Bernie progressives want fighters that will fight against this trend. If single-payer will cut the insurance bill by half, and will guarantee access to everyone, and if every other developed country in the world has figured out how to do it.... DON'T FUCKING TELL ME THIS POLICY IS TOO MUCH TOO FAST (because some lobbyists is whispering in your ear about campaign donations). If you are that kind of Democrat, you are NOT what the country needs right now.
