What’s the fastest way?

What would be the fastest way for the government to inject money into the economy?

Could it possibly be to not take the money away from us in the first place?

Tax cuts are the fastest way to get money into the economy. Anybody who tells you different is a) an economist, b) lying to you, and/or c) lying to you because they want to take your money to buy your vote by giving some of it back to you. Don’t fall for it.
