And this can push a person in a direction from which they may never recover, as instead of accepting their mistake and repay the loan, gamblers may be lured into asking another loan and try to recover their money this way, and once they finally realize the mistake they have made, they will notice their debts have grown to a point in which it is impossible for them to pay them regardless of what they do.
It would be irresponsible for a gambler to borrow money and promise to repay if he wins, that's out of this world condition, it should something that a lender could expect he'll get as a collateral, normally fixed property or vehicle. Gamblers who have that kind fo mindset in gambling would likely suffer the worst financial problem, and since no lender would just lend money without assurance, most likely the borrower would end up selling his properties just to be able to pay, while some even go homeless.
After all, gambling is not a place to make money, it's just entertainment, I gamble but still have limits. Even now I rarely gamble, because I am getting bored with what happens in gambling with the amount of losses that are obtained it is clear that this is just a game not a regular income. So I will not finance a gambler it is better to finance someone who will start a business or business which of course will produce something later.
