Reforming the IRS as an organization doesn't work when it's tax law that's the problem.

Tax law has issues, but deficient analysis, audit and enforcement against richer, more complex files is a huge issue.

Why fail to fix one over the other?

It’s part of a solution, not the entire solution. But even if you improved tax law you’re still going to need a well-resourced and highly skilled IRS capable of properly auditing multinationals and the very wealthy.

What leads you to believe increased funding would be directed toward regulating the richest and most powerful people/companies (i.e. the biggest financiers of political campaigns on both sides of the aisle)?

The OPs statement was that more focus needs to be on improving enforcement. I simply pointed out that improving enforcement, by reversing the budget cuts and consequent drop in audit capability within the IRS, was part of the current administration’s policy.

Whether their proposed changes will actually work is another question, but it’s wrong to say there’s no attention there and that the debate is only about raising taxes.

I can’t say I understand the downvotes I received for saying that.
