I always thought "trickle-down" economics was about giving money to businesses via tax-breaks and that money would make it's way back to the people as wages. We know this doesn't happen and companies do stock-buybacks with that money.

Here, we're discussing a different paradigm: interest-free money vs free money. The issue is that interest-free money has little to no use for individuals. They can't put that interest-free money into an existing business and reap the returns. That's why most people just use that "interest-free" money for stocks (margin trading) and even then it wasn't fully interest-free.

The fundamental issue is how to give individuals interest-free money and have them see returns. Maybe using that money toward job training, or starting incubators that find small businesses and infuse them with money, mentorship, etc.
