British children have parents that have been paying tax their whole lives and will continue to pay their whole lives after their children have finished education.
Funny, in a lot of th schemes where I used to live there were brigades of rabbit-style-breeding chavs and neds who seemed to want to repopulate the world befor they hit 20. Many of these indigenous tribes had not worked for a good while... so how were they paying tax.
Another point... a lot of the immigrants who ar working are paying into an NI fund they will probably never use. It'll help pay your pension when you retire from the call-centre job you'll probably have after graduation.
And nobody is criticising you for getting an education... just for being a prat.
