Biden forgave student loans and conservative SCOTUS stopped him. Dems passed ACA and expanded Medicaid and CHIP. Republicans cut them both.

I could go on but I'm sure you know all this. Dems aren't perfect. Nobody ever is and it's unreasonable to expect that. They have pushed legitimate progress. Republicans almost exclusively cause harm to protect the upper class. Retreating into cynicism is just a way to absolve yourself of any civic responsibility.
