The problem with this tax law change is that it really changes nothing, as the progressive income tax code is designed not to raise revenue but to redistribute existing revenue. Some taxpayers will pay less and others will pay more to offset the lost taxes from those lucky enough to pay less. Just like Obamacare, if you file as a single person you will likely subsidize those who file as married. The progressive income tax code is really unfair to millennials because of their filing status but it has always been this way and always will be.
