That "tax hike" would almost all get spent, and probably pretty quickly, because the overwhelming majority of it would be going to people who live close enough to hand-to-mouth that the differences are academic.
So is that pulling $3T/year out of the economy or pumping most of $3T/year into it?
Step 1. Pass 3T worth of taxes and spending cuts.
Step 2. Give everyone $1k a month.
Step 3. ???
Step 4. Poverty disappears, the economy grows by leaps and bounds.
It's a utopian vision. Tantalizing, yes I can empathize with people who like it. But let's not forget that Utopia comes from the Greek words "not" and "place". A utopia is something we all desire but does not exist. The pursuit of which has led many societies to ruin.
If we're going to premise the "health" of our economy in no small part on the movement of monkey status points, then move the things.
It's "trickle-up", not "trickle-down"...
Which is fantasy. It's not people paying the taxes it's a VAT that Yang's advocating for. This is money directly coming out of economic activity.
Have a nice day.
So the plan is to pass one of the biggest tax hikes in US history (probably the biggest one during peace time) and then keeping our fingers crossed hoping for rapid, consistent economic growth following said massive tax increase. I think I'll pass.
