Re: works both ways but certainly works.
With respect, your wife's situation does not compare that of kids today. My middle son is in his third year at uni and is in the second year of those taking on the debt required to fund their studies. Unless your wife did all of this studying and travelling in the last three years (a truly remarkable achievement) then your comments don't amount to much.
Today, the undergraduate period is where the costs arise. If your wife went on to study for a PhD then today, just as in previous years, there are grants to help. But universities offer only limited bursaries to mitigate some of the undergraduate study costs even for the most able students who are also from a less advantaged background.
By contrast, my eldest son who has now completed his degree course and is now working has almost no debt.
