Best case against
Tuition-free college raises enrollment without raising completion, and federal adequacy funds substitute for state money rather than adding to it.
The author's response
The evidence for tuition-free programs is encouraging but not uniform. Statewide free community college programs have generally raised enrollment, with more modest and more variable effects on completion. The lesson for design is that tuition is not the only barrier: students who drop out usually do so because of living costs, work schedules, and weak advising rather than tuition alone, which is why the proposal pairs tuition coverage with completion supports and funds institutions partly on the basis of completion and earnings outcomes.
What remains uncertain
The chapter therefore treats completion as an empirical test: if six-year completion does not rise within a decade, its own failure trigger shifts funding from tuition coverage toward living-cost support and advising.
