To get a similar effect with precisely no upending of current economic thought, I was intrigued by Cory Booker’s idea of (essentially) cutting a check for some amount for every baby at birth, to be held on account until age 18, growing at a set interest rate of 3%, and afterwards could only be tapped for health care or a house downpayment.

Except I would have done him one better, by (a) sticking in 10K instead of 1K (similar to your “create the money when needed” idea), (b) coming up with a way to force in additional donations each year (1K), but (c ) investing the money in a market index to get better returns.

So, quick calc for 10K at birth with 1K added per year at 9.8% average market return (average return for the last 90 years) = $98,505.

Pretty good kickstarter for building wealth through home ownership. Of course, house prices would inflate based on increased demand…so……who knows what the net effect would be.
