1. Jobs and Growth.
2. I didn't say we recovered from the Great Depression in one year. I stated that we recovered from the 1920 crash in about a year to a year and a half.
The tax cuts have helped grow the economy, and we've actually collected more tax revenue with the cuts from everything I've read on the subject.

Nominal increases below the rate of inflation mean that the value of revenue collection has actually declined in real terms. By our estimate, total revenue over the time period in question has actually fallen by 1.3 percent after accounting for inflation in the last year. Measured relative to GDP – a sensible way to measure since a steady tax system would be expected to capture the same share of the economy year-after-year – we estimate revenue has fallen 3.8 percent. Finally, relative to the increases that had been expected from population growth, inflation, wage growth, structural elements of the tax code, and other factors, tax revenue is down by roughly 5.5 percent.
