A janitor at Boston College worked the overnight shift for more than 20 years. Not because he had to. Because the university has a policy that lets employees' children attend tuition free. Fred Vautour took the job with a plan. If he worked at Boston College, his kids could go there for nothing. All they had to do was get accepted. All five of them did. His oldest, Amy, started in 1998. His youngest, Alicia, graduated in May 2016. One by one, each of his children applied, got in, and earned their degree from one of the top private universities in the country without paying a dime in tuition. The family saved an estimated $700,000. Vautour cleaned bathrooms and mopped floors on the graveyard shift while his children slept in dorm rooms down the hall. He never asked for recognition. He just kept showing up, year after year, so they wouldn't have to carry debt. Five kids. Five degrees. Zero dollars in tuition. All because their dad picked up a mop
