Who cares why you go flying, I dont care of the pax/cargo in the back I just want to fly and if i'm going around the world doing that i'm not complaining. And you say gambling destroys lives maybe but it also supplies millions of jobs and infrastructure and money to the economy. Money that those employees use to live and pay for school for their kids and the list can go on... so you could also say it creates/saves lives.
