It would be nice but this is just political grandstanding. Too many accountants and lawyers depend on the byzantine tax code for their livelihood.
CPA’s and attorneys do not now do productive work when they are taking care of tax-related matters.
There would be a huge dislocation for these folks of course, but in the long run it would be vastly better for the country as a whole.
And likely for many of them as well over time.
Productive work instead of wasted effort on byzantine governmental compliance. Always the better choice.
Things can change dramatically when the people demand it. It doesn’t take years, or months or even weeks. Example: the fall of the East German Communists.
And politicians.
Politicians and their staffs get paid to put in all those exemptions. It's a huge industry.
