Is There a Way to Increase the Tax Rate on Human Capital?

There isn't much evidence that this can be done effectively at scale. It gets more complicated because then if you increase the threshold for the phase out, that can attenuate some of that a winlarge is probably going to be a wash onon the growth front. And it's expensive. We double the child tax credit in the 20 17 tax law and increased eligibility for it. That cost almost 600 million dollars over over ten years,. Without, probably without much of a positive growth, in fact. I'm not sure that that can be effect scalable.
