Growing up during the US war on the Iraqi people, the jingoistic coverage in media for all US wars, then the subsequent alienation I felt after I started working, is the main thing that turned me to Marxism. Essentially, when the extremely untrustworthy warmongers start calling everything they dislike, "communism / socialism", then it must be worth looking into. And I found that there was good reason they carefully steer populations away from Marxist literature, and deem it a heresy: because its a clear and straightforward description of how things actually work, and it threatens their fortunes. Nearly every communist grows up in liberal-dominated cultures, and goes through their own process of rejecting the world that enshrines property and profit over human lives, and how it affected them personally. Their stories are all worth listening to.
I've worked in many different industries in software, and found the same issues in all of them, and just lost patience, especially seeing that all the work I did creating proprietary software was essentially thrown in the trash, and societally useless. I'd much rather be paid very little, and contribute something positive to the world; time is our most valuable resource, and we should spend it doing things that improve the world, because there is so much that needs doing.
