While I thought that the comparisons with the working conditions of American major carriers a bit over the top (given the state of the American airline industry, I certainly wouldn't hold them up as a shining example to emulate), the initial premise - to do one's homework and know what you're getting yourself into is certainly valid. I can't tell you how many times in the last few months that I've been with a new guy (invariably from the U.S. and almost always from regionals) and as I relate some of the more onerous practices of our employer, just watch their jaws drop. They didn't have a clue.
It's not up to me to tell anyone whether they should be happy or not but anyone considering coming here owes it to themselves and their family to read the fine print and be aware of the negatives as well as the positives. If they then make an educated decision to come to Emirates, they probably will be happy and will certainly be easier to spend the night with somewhere over the Indian Ocean.
But then again, they are nice new 777's........
