Bernie opposed the Iraq War which cost a few trillion dollars. More in fact than the entire student debt, just to put it into perspective, not to make any recommendations. Bernie condemned Hamas for killing Israelis but Israel more strongly for killing huge numbers of Palestinians most of which are women and children and do not match the descriptions of the Hamas forces. Using a traditional definition of the 'Left' as favoring improved conditions for the poor, this country is now under Biden moving to the right in that sense, of rising rents and house prices, and declining prospects for being able to earn enough money to survive. Using the new definitions of the Left as favoring defunding the police and flooding the country with immigrants, I would be interested to hear his stance and reasoning.
Defunding the police is not a position held by a significant number of people, even on the left. There was a year or two when it was more popular, but I would never have called it mainstream left. Flooding the country with immigrants? Also a mischaracterization of the left. It's more a lack of (or at least reduced compared to the right) concern about numbers of immigrants, and rather concern about the welfare of them as people. But yes, Bernie is more of a true leftist than Biden. I think I agree with most of his ideas, but they're not all presented here, even the ones on the poll.
Bernie is old Marxist. Marxists can think only in terms of their ideology. Therefore they are wrong about 90% of the time because for them every evil in the world is caused by capitalism. This is true of Bernie except when he is acquiring more houses and personal wealth. Then he is a capitalist.
Leave it to conservatives to exaggerate how far left any leftist is. But he's definitely to the left of other mainstream American politicians and is more like a European politician - most of which are to the left of America, but not fully socialist. He wants to reform capitalism, and regulate it, not discard it.
Traditionally, the right wants minimal regulation and therefore reforms. Corporations self-police. There has been some anti-globalism injected in lately, though.
I have not had any contacts with true Marxist believers lately, but their usual analysis starts with, “The problem is capitalism … “ From then on it’s all boilerplate.
