They can't get of themselves and there's no resource for them anymore and that's why they're borrowing money to gamble.
Loans are intended for critical budgeting and perhaps meeting market objectives. We're never satisfied with what we have; if we make an excessive amount of money today, we'll be even more frustrated and desperate the next day, because we keen on doubling whatever initial money we generated already. Creating extra money to pay bills without depleting our basic funds will result in significant savings for us in the system. We bet what we can afford to lose in the system and avoid staking what would make things extremely difficult for us.
