> At Lambda, students pay nothing upfront. But they are required to pay 17 percent of their salary to Lambda for two years if they get a job that pays more than $50,000.
This appears to create a cliff:
If you make $50000 a year, you keep $50000 a year.
If you make $51000 a year, you pay 17% ($8670) and you keep $42330. That extra dollar cost you a ton of money.
It really ought to be a marginal rate like tax brackets.
