Name a single person here who claims that tax evasion is not a problem?
Cutting taxes is not a laughable concept if taxes are applied inconsistently and aggressively against those whom it is applied against. It is possible to have lower tax rates, but more evenly spread out so that everyone pays. Rather than potentially punitative rates against the honest and nothing against everyone else.
Please. You're going at it backwards. First you have to apply the existing laws consistently - THEN you can think about changing the laws.
You're just trying to slap bandaids on a gangrene wound.

And watered heaven with their tears:
Did he smile his work to see?
Did he who made the lamb make thee?
