Gates bemoans US visa restrictions | The Register - this article caught my attention becaouse of a sentance near the bottom - "...in India, 40 per cent of students take engineering degrees, against just four per cent in the US." - I suspect the comparison with the UK would be similair - you gotta watch the sub-continent because as it's population becomes more educated they will be disproportionately more advantaged in the 21st century.
