You mean, like now.
I'm paying for college now, and in a year, I'll be paying for two kids, and due to close age spacing, I'll be paying for two until 2024, when I drop back to one.
I'm glad I can afford it, but, truth be told, the pricing is absurd, the differences between private schools in the same brackets (Bates-Bowdoin-Colby, Williams-Wesleyan-Amherst, Bucknell-Lehigh-Lafayette, Kenyon-Oberlin-Denison, etc) HAS to result from price-fixing.
If it were free, everybody would be paying much higher taxes, but the travesty of non-STEM "education" really wouldn't change all that much, IMO. The horrible results predicted by the anti-Bernie people are already here, in spades.
