How very political, communist, capitalist, unionist. Crikey, I didn't realise the seniority system was based on the free market, I thought all that queueing was done in the Eastern Bloc. I think you are confusing capitalism with protectionism, something the US of A is very good at.
Every other profession uses the free market, some of them even have unions. The seniority system seems more at home in North Korea! Survival of the fittest, nope, survival of those at the front of Q. I guess all those dinosaurs became airline pilots!

p.s. I'm just off to play tennis, if I turn up first I should be entitled to win the tournament. May the first man win, that's what I say!
