that's basically how the world works does it? not just here in Qatar.

which is,

the greater amount of money you spent on your education, the better chances you get it back thru salary, but not nescesarily always.

and another thing is, your salary depends on how your way of living goes back to where you get your education.

so compare cost of living and education costs in UK against in PHILs or INDIA or elsewhere.... and we'll see the big picture.

...
that is just my humble opinion :)
