This discussion is showing that smart people on both sides of the aisle recognize something needs to be done about these important issues.
Trump talked a big game about "draining the swamp" and working in a bipartisan way on priorities like infrastructure, which is why I was actually excited about things he said when he ran in '16.
Sadly, Trump has instead chosen to pick a lot of contentious fights over things like an unaffordable and impractical border wall, and otherwise just sits on his ass and tweets. Turns out when Trump said he would "run the country like a business," what he meant was that he wanted to run it like his personal fiefdom, which is what the Trump empire was. But the U.S. government doesn't work like that. You have to be patient and strategic, build coalitions, and achieve buy-ins from multiple parties before stuff gets done. You can't just shout commands from the top and get people to follow.
I think candidates like Sanders and Warren would take the fight right to the entrenched, moneyed interests that are holding our country back. And they have the track record in government to know how to get stuff done using the levers of power. I don't agree with everything they say, but they are certainly the two "change candidates" of the cycle.
