That's the thing though, they aren't trying. If anything they have INCREASED the number of special deductions, it's just that they have made them for rich people only. In addition, they have designed this bill so poorly that tax lawyers and accountants are going to have a field day finding new and inventive ways for their clients to avoid paying taxes.
Mark my words, this tax bill is going to cost a LOT more than they think because they have not done the due diligence to prevent the system from being gamed. If they are trying, then what they are trying to do is give large gifts to their friends and donors that people like you and I will pay for. Total scam.
It's not lack of due diligence. They know what they're doing. Deficits don't matter when they're caused by tax cuts at the top. Their numbers are just a sales pitch & a come on to eventually crippling the govt with debt.
