I'm not going to say most Democrats aren't capitalists and in corporations' pockets. But one party got ACA passed and tried to get some student loan forgiveness passed. Along with a whole number of different laws passed for worker protections and similar over the last few years.
On the other hand, Republicans have Trump who tried to pass Schedule F for government workers which would have taken us back to the spoils system where Presidents hand out government appointments, jobs and ambassadorships as rewards for loyalty. FYI we got rid of this system after it directly caused President Garfield's assassination. That's just one of many anti-worker, anti-poor, and anti-people reforms the last Republican president tried to accomplish. We don't even need to touch the entire Republican party's fascination with stripped rights away from women and trans people.
Both sides is bullshit.
