They all have the opportunity to achieve. Some people obviously have more advantages, ie financial backing from family, parents that give a shit, etc... Some people gotta work 10x harder but they can still come out way on top.
My buddies ex wife immigrated here from russia when she turned 18, went to school, graduated with a masters in structural engineering, paid off her student loans, etc. she now makes six figures doing r&d for building materials. She also got a real estate license and sells homes at night, has reinvested all that into two rental properties and shes looking for a third. shes in her mid thirties now..
she ain't even american and she managed to pull off the american dream. From birth, I've had every advantage over her and shes still more successfull than me. Stop your bs, you are where you are because of your own choices in life, not because of someone elses choices.
