But without such colleges -- which are truly dedicated to educating disadvantaged students and not just accepting a small percentage of them -- our country will continue to suffer the results of decisions by uneducated workers and voters. And it will lose the potential for significant societal contributions from the students who are able to attend these colleges and thrive as the result of all they’ve learned there.
