This is 100% the story. The IRS can help make sure everyone is playing fair if we sufficiently fund them. And they can stop policing all the little issues and go after the big ones if we sufficiently fund them. AND sufficiently funding them is expected to increase tax revenue above the cost of funding them.
It's the most obvious and should be the most bipartisan approach. It's introducing no new taxes, it's equitable, it improves revenue (which could allow you hypothetically cut taxes.) It drives me up the wall that this isn't just a fast, handshake and proceed bit of legislation.
