How are people supposed to become experienced when no company will offer to train them? (Credit to u/DangerDan93 via Reddit)

I'm so sick of this! Everyone keeps saying that the trades are desperate for workers, but no company wants to train them. They expect you to be in a good life situation to be able to go to school for the experience, but a lot of us have neither the money nor time to do so! School is expensive, you don't get paid for it, and most of us are one paycheck away from becoming homeless. How is this system sustainable?
