"If college were free then money wouldn't be the answer."

But college is free. MIT is free for people who make less than $100k/year. Stanford is free for people who make less than $100k/year. Amherst is free for people who make less than $60k/year. Most other private colleges will give full rides for people of the income level that this article is talking about.

Is money still the answer?

you need better K-12 education for poor areas in order for them to qualify for these "free" university programs.

Yeah, that's what I see as the real problem. I'd really like to see more attention paid to preK-12 education in poor areas, because by the time these kids get to be 18, it's generally too late unless they have heroic individual will. But that means targeted spending - it doesn't necessarily take a lot of money, it takes a moderate amount of money that's well-spent on programs that make a serious impact.

I'm fairly certain it extends to international students as well - I had friends at Amherst whose families made less than $3000 annually (that's like 1/4 the poverty line in America), and there's no way they would've been able to afford it if they didn't have some serious scholarship money.

This is only true for the best schools with a decent amount of money. As bloomberg noted in a piece last month, a lot of schools on the cusp are in big trouble financially and depend on tuition to make up the difference. For most of these schools, students making under whatever the line is, don't get full aid like they might at Harvard, MIT, etc.

Also, this only extends to international students at, again, the best schools. When I applied for college several years back, I think it was only five schools that were need-blind to international students (they were also very generous with that aid). There might be more schools that do so now but I can't imagine it's substantially more.
