When you are depending on someone for assistance because you want to gamble it means that you are risking what you can not afford to lose. Why because you don't have the money to gamble but someone have to give it to you before you can stake.
But when you have jobs that pays you money so well and you are gambling it means you are risking what you can afford to lose. Why because ones you lose your job will give you another money.
However, many people would say even if you have jobs but you are staking higher it also means you are gambling with what you can not afford to lose. Moreover it's true and I have to dauth but I have a feeling that ones someone that have a good paying job is staking more than what he can afford to lose, there is no different between addiction there.
Everyone's financial health is different, maybe when you earn 20 thousand dollars, and use money to gamble $2000 will not affect as long as your needs and needs are all met, I guess it doesn't matter and you will not remember it so much, but it is different from people who earn $200 then use $20 to gamble, in terms of sufficiency it is still lacking which will give illogical financial calculations and you will not be able to afford to lose $20 to gamble.
The scale of income affects how much you can use money, and you become prepared to lose, the average person who is not prepared to lose is those who use more money than their income.
