Jealousy is a pretty bad thing. Rather than look at it from "He's tall and I'm short and that isn't fair". Look at it like "He emigrated to a wealthier nation and I want to do the same, so I know it's possible". Seriously don't pick USA if you have a choice, but it's better to look at it from that way.
Elliot Rodger had a multi-millionaire dad. He posted pictures of expensive cars and stuff. Now look where he is. You can't judge things looking from the outside in. His dad can go bankrupt tomorrow.
Apart from that, these people making your blood boil is extremely helpful since now you have the motivation to make something of your life. So make a plan, research how to attain what you want and forget about losers posting their fake life on the internet as by that point it adds stress that you don't need.
Lastly, a big secret: Life isn't fair. The universe doesn't care about you, me or anyone else that's here. Throwing a temper tantrum because "I'm a good person, why can't I get what I want when assholes get everything" is pointless because the universe doesn't care. It's just there and the best part about it is that if it wasn't you wouldn't be able to throw temper tantrums in the first place.
So admire those that are successful and attempt to learn from them, see what they do right. Realize what they do wrong. Do all the right things and avoid the wrong ones.
