Good for you Tom.
Given the position you are in, it absolutely was the right decision- I'd rather be in Delta with many years seniority then here- not so much because of the job so much (though clearly the moneys better) but because of the location.
But that option isn't available to any but a very small percentage of the population- INCLUDING a huge number of US pilots who had no option then to take the terrible conditions offered by the regionals as they were the only jobs going, thanks largely to the cowardice of the pilots at the majors, and indeed for them EK was a huge step up.
Question is, why do you think it appropriate to boast about it, while denigrating those less fortunate than you?
Had you not been born in the US, had your country not had it's anticompetitive, protectionist bankruptcy laws, or had you chosen to go and work for one of the majors that has since gone out of business, you wouldn't be where you are.
You've been lucky.
Lording it over and insulting others because of it is hardly a mature or professional thing to do.
