I feel like your political views on what is or is not 'feasible' have been
anchor-effected by the status quo and Bernie is bringing so much good to the table that you can't understand how it is possible, because everything has been bad for so long; if such goodness was possible why hasn't anyone else brought these policies to life?
The vast majority of Americans are in favor of the vast majority of his policies, by no small margins. These policies
are realistic and can be paid for.
Every other developed country in the world has orders-of-magnitude cheaper universities (some even pay students living stipends so they can focus on their studies) and a national healthcare system on par or better than the U.S. while paying
less than half of what we pay. I didn't watch all of the Joe Rogan interview, because it's 65 minutes long, but he did go over very specifically how to pay for some of these programs and he had smart answers, like a tax on wall street transactions (like 0.05% per transaction or something super tiny) through volume raising great funds and also doubling as a disincentive for speculative trading.
