From what I can tell the majority of proposals for student loan forgiveness would have income limits and would be limited to undergraduate loans. Both of which would exclude most practicing physicians.
I don’t necessarily agree with student loan forgiveness, but I think most of the arguments against it are not being made in good faith. I think the people who don’t like it basically don’t want it because Democrats want it. Democrats want it because activist progressives want it. I am not convinced it is a great policy for the country either way, but it’s relatively small compared to the massive give aways Trump gave to corporations and the wealthy, or that both Trump and Biden gave to basically the whole country (but with much of it going to wealthy small business owners) during Covid. If there is a principled reason not to do it, it isn’t a principle either party appears to have held as recently as 2020/21.
