First - "poverty" is up to $14k per year. Many of those people are "poor" - but probably not the majority, and definitely not even close to all.
Second, billionaires have almost $7T in wealth - the top .1% are at about ~$20T.
They didn't get any meaningful percentage of that by taking pennies off of 45M. You'd need to take thousands. And they just don't have it. That's almost $450k per "poor" person.
That's more than the median HH wealth in the US.
If you look at the "actual poor" - you're likely looking >$1M per person.
You simply cannot "steal" that from the "poor" (who have almost nothing to steal, by definition).
Even if you amortize that over decades - it is just not how it happened.
For one, there aren't 100m poor people in the US. Not even close.
