Real quick, the $1000 530A account, if you put in just $1/day, $30/mo, on top of that account, then you get out ~$12,000 at the end of 30 years (assuming 5% interest rate). Which, yeah, that's enough to start a very small business (lawncare, blacksmithing, etc).
The stock market is at ~9.5% returns historically, inflation is likely at ~3% historically, so assume a little higher at 6.5% and that $1000 with a dollar a day increase is then ~$14,800, inflation adjusted.
If you go up to ~$100/mo at 6.5%, then you get ~$42,000, which is an honest start to a small business or college tuition.
The little extra per month really adds up here!
I may not like the administration for a lot of things, but this is one thing that I can really get behind.
This is largely separate from your point, which is good, but the $250 is for kids that won't get the $1000. The $1000 only goes to kids born between 2025 and 2028.
