Wow! I waited at boarding time, I did thousand works at home and after taking flight I cant recline my seat? Why? Arey!

Why cant people blame the greedy airlines who put 1000 seats in economy section instead of 500? Airlines work being inhuman and poor traveller suffers. I am tired and I wish to take nap. There is no leg space and no back space....so better let me stand for all time instead of that tiny narrow badly straightened seat na.
