I wouldn’t exactly call 4% booming
That's a huge number for the largest economy in the world.
I would measure it by sales and income tax receipts at the State level. When these go up, they reflect true economic activity as people can't avoid these taxes and the States can't easily fudge numbers.
If zero can keep government impediment away from business, i.e. energy development, construction and other CAPEX; we may hit 4%.
That's a big if. The greens want to reduce economic activity, but zero does not owe the greens as the greens would vote democratic no matter what.
