If you are just going to carve out a bunch of exemptions, which is what actually makes that tax code difficult in the first place, to end up with the same outcomes that we have now, why change anything? It would actually be even more difficult to get the exemptions right since there would have to be more, they would have to be higher, and their phase outs would be more complicated.

Also, a single "family" of one, pays more in taxes today then say a family of four with 2 kids earning the same household income. Apologies ahead of time if I misconstrued your argument.
