Taxes are what they are and part of the reason they are what they are is because of tax fraud. (It may be a small amount compared to the waste caused by crooked politicians but it definitely contributes.) You may not be promoting tax cheats it but you sure seem to be justifying them. Like I wrote before, if you feel that politicians are stealing from you, you have the right to vote against them.
There is no way to create a tax system that is fair to everyone. What people are trumpeting as fair share will definitely not be fair to many families. Are you ok with anyone cheating on their taxes when they feel it’s not fair for them? Did the founding fathers write that anyone who feels that taxes aren’t fair for them have the right to cheat on their taxes?
If someone feels that Yeshiva Tuition is too high for them (or they don’t like the way the Yeshiva spends it’s money) and the scholarship given to them by the school isn’t enough- do they have the right to lie about their income on the scholarship application?
(As a side point- I was told by a lawyer many years ago about how I could legally lie to save myself hundreds of Dollars per month. He said that the law in the case is that lying isn’t illegal but it gives them the right to sue me for all ill gotten gains but they’re too lazy to do anything about it. I asked a shaila and was told that irregardless of US Law it’s ???? ????? as it’s stealing from all stakeholders and I’d have to repay every single one of them.)
