Yes Bill Gates did travel by economy class when he was the richest individual in the world, however he also paid $130 million on a house which could also feed the poor and has the largest Yacht in the world. TUQ's own institution MQ focuses on achieving social equilibrium by educating the poor and providing food and shelter for them. Their is a reason why his Mawlid is the largest in the world, where even foreigners come to celebrate. Personally, I don't support his political party although at least he is proactive in trying to change Pakistan. By the way he earns his income through a ceramics business which he co-owns with his partner 30 years ago.
