And working at a dead end job - at $1.25 an hour (in today's dollars that minimum wage or less) - that had no possibilities of advancement. He kept getting fired, couldn't hold a manual job, got fired from the one job - the photography one - that he thought had potential. He defected to the USSR, came back, failed at everything he tried, tried to defect to Cuba. He entered the Marines in 1956 as a PFC and left three years later as a PFC. Wife, two kids who have to live apart from him because he couldn't provide for them. He's 24 not 18.
He wants to leave the US because he can't make it here. He's a failure by any measure - he speaks Russian? - but he blamed society, the US, the FBI, for it.
He reportedly got a better paying job offer at the airport before taking the Book Depository job.
Why he chose to work that low paying job at the Book Depository, we don't know. But what evidence is there that he couldn't have gotten a better paying job?
How many Americans who were fluent in Russian language during the Cold War would be "unemployable"?
And again I ask, is it normal for someone to view themselves as a "failure" at such a young age? He didn't know he would be killed at 24.
It seems like you guys are projecting your own biases onto Oswald. Including the conservative implication that his being raised by a single mother somehow turned him into a sociopath. Being raised poor by a single parent isn't easy but 99% of people who grow up like that don't become violent criminals. So it looks like you guys are grasping at straws again...
