I don't know if you're being deliberately obtuse but that is some ridiculous hyperbole. If it makes it easier for you imagine that all university education is state subsidised via loans that are not repayable so long as you are working in the country but must be repayed otherwise in proportion to the amount of time you spend working in another country. Alternatively you could be required to work for a minimum number of years in your native country in order to pay back the loan. I know of many schemes for educational loans that do just that.
