Also, it's all relative - the chances are that if you're complaining that your life is oh-so-difficult, there'll be someone nearby who'd envy your life.
And to answer your question with a question... Why are you asking?
why do you think someone "complaining that [their] life is oh-so-difficult" predicts that others will envy them?
You've kicked off a good discussion here... what do you make of the responses so far? 68Y, 37N.
your attitude of "An easy life would be dull" is very productive and has probably been strongly selected for. at the same time, i'd like to point out that evolution does not select for happiness. i wonder how much you really appreciate those difficulties while you're dealing with them, vs. reflecting on them. i think we should be weary of struggling for the sake of surviving.
