I agree that Dems need to favor small businesses more, I think it just means taxing at higher income levels to create more revenue for grants and funding.
Medicare for All would do more to help small businesses than just about anything.
I always find it ironic that the very people who are always worried about "the economy" don't seem to realize that the privatized health "insurance" model is an enormous drag on the economy and is bad for basically everyone. Everyone except health insurance companies that is.
