This is how a poor person imagines riches happen to befall any of us. They just happen, one lucky day, you dig and you find a pot of gold, or a ton of pot.
Its a reaction based worldview, where you do not control your own destiny, and wealth is something drained from you, that comes in large quantities by chance.
You do not manage what you got, slouch through a horrible existence to slowly improve yourself. Because that is what the others do, the chancers feed upon. The people who lead that life, are the customers of the drug dealers, those who have the chance to get ahead at the cost of others.
Riches are taken in large quantities by others, with stick up like scenarios- your landlord squeezes you for everything you got, the repair shop rips your wallet open, any accident makes you a indentured slave to the insurance company.
So in a hopeless life, daring to hope, when you get a risky chance, seems actually reasonable.
