The Mat is an idiot. The country doesn't discriminate you. It doesn't stop you from becoming a doctor, accountant or engineer.
It is just the preference of the employer and some who are biased.
Just like some people just dun like to have chink as friends and prefer mats or Nasi Padang stalls prefer to give discounts to Mats than any other race.
Does it means that Nasi Padang stall are discriminating against other race?
The answer is obvious. By charging non-Mats higher prices, that is already clear-cut discrimination!
