Supply side economics are on their way out. We have found out, the hard way, that giving money to banks and then to businesses, it puts money in the hands of people who can be very political about their business dealings. Both non-whites and conservatives feel discriminated against.
edit: Reaganomics – give money to a bunch of businessmen who can stock their shelves full of products. Then hopefully enough workers can find good paying jobs to buy the products. It’s obsolete. It’s extreme. HW was against it. Nixon was against it. Democrats should stop it.
