This doesn't seem to make much sense: You're against a policy because someone lied and didn't implement it when they said they would? You can be for taxing the rich and against people who do otherwise simultaneously.
The burden of proof is on you then. For you to be able to say that, you'd have to enumerate all possibilities and then provide evidence why each wouldn't work. In the meantime, it seems obvious things could be better without needing to be perfect.
I am sure some figure out ways, but you have to go in dodgier places.
This is a new development is the last 10-20 years, so there is progress. It should help people trust the system is getting fairer.
If one is against taxes, and uses lack of enforcement as a reason, I smell dishonesty.
