Undergraduates with family income below $200k will be tuition-free at MIT

This is a great step in the right direction. I can't speak directly for MIT, but there are issues with how these programs don't apply to parents with small family businesses. My parents had a small business, with my father taking home a salary of $XX,XXX. Duke University used the business assets to determine the EFC (expected family contribution) of literally 90% of the salary. Essentially saying to sell off the family business for the college fund, which was a non-starter.

Small businesses are allegedly the backbone of America, and I feel these tuition support programs overlook this segment of the middle-class.

Isn't the entire point of these assessments to look at total assets, and not just annual income?

I dont think this was an oversight or mistake. I think the expectation was that yes, people should sell assets if they have them .

Should they also cut their kidneys out and sell those too?

For someone not in your system, the expectations that seem normal to you sound absolutely insane to others.
