The best way to get rich people to donate and campaign against something is to exclude them from it. A $1500 tax credit for someone making $1m doesn't amount to much but psychologically they'll still fight to preserve it because they benefit from it. Besides: if your goal is to encourage people to have more kids then even someone making $111k/yr still has to pay for childcare which can make it a career vs child conversation or a "push goals back a few years" conversation. Raising kids is hard enough without having to make tough choices or materially reduce your lifestyle (beyond the unavoidable time commitment). If you don't care either way then go ahead and clamp down on the program or eligibility. For however much you tighten the screws you'll have that many fewer people having kids or dropping out of the workforce.
