For all the dumb shit she does say here, she isn't wrong that having kids is retardo expensive and offering cash benefits for more kids does not appeal to middle-class families. Unless you're poor and don't care or have a stay-at-home parent or a live-in relative to watch the kids, a cash bonus is never enough money when you look at childcare costs overall - and I'm not even talking about daycare.
The way to make childcare affordable again is to make shit less expensive in general. Trump is trying to do that with his economic re-orientation. Whether it works or not remains to be seen, but the Democrat plan is tax more and money printer go brrrrr, so people are willing to give Trump a whirl. Democrats are also obsessed with daycare. It is critical to socialize young children, but their solution is always the service industry and not to address the underlying issue that kids require some personal sacrifice (i.e. you will not have kids who like you if you and your spouse work full time) and that decades of wanton spending has made the economy shit
