It's $2000/yr bonus for minimum wage warehouse employees, not spoiled engineers.
--most people working in Amazon warehouses are employed by temporary staffing firms, not Amazon
--most people working in Amazon warehouses don't come anywhere near 3 years of tenure before quitting or being fired
--reimbursement is limited to $2,000/year for four years, while $5,000/year is pretty much the minimum direct cost to take such programs
--the program is limited to full-time workers, so only those who can take classes while working full-time and mandatory-or-you-get-fired overtime can partake
