He needs a lesson in being humbled so he'd smarten up. In your case, haymura, you came back knowing what it's like over there but to say that it was "the worst decision you ever made" I feel is a far cry. If you had just stayed here, you would have never known and now you can confidently say

All too often, kids here grow up being comfortable and when a wrench is thrown their way, they give up on life rather than take on the problem head-on then post their stupid ramblings in the "Speak It Out" thread in the Relationships Forum. Fuck that shit.
In life, there are no such thing as poor decisions. Just uninformed ones.
