That shows more irresponsibility, and that happens due to gambling addiction. If someone tries to increase their income because their salary is too low, that is a dumb decision.
It's right that if their salary is too low, they can work harder, take mulitple jobs and increase their salary and income, but it is terrible if they want to increase their income not through working harder, taking more jobs but through gambling more actively.
Everyone knows that gambling is risky, and if someone risks their salary to make money, that is an irresponsible and dumb decision. Responsibility is not enough; one has to have a brain in one's head.
Gambling is risky because it is game of probability and you have to fight against bookies, game providers, gambling platforms too. On top of that you must beat yourself, control yourself, and gamble as most responsibly as possible.
If you become gambling addictive, you will be done with your big or small salary and income soon.
Who risks their salary to make it bigger just because it is insufficient? Once, I risked my salary to gamble because it was in crypto, and I wanted to have fun. I ended up losing that, and I learned a lesson. I have responsibility and I never repeated the same thing.
Salary is to save for spending and emergencies or investment to increase your wealth with time like invest it in Bitcoin and hold your bitcoin for some years. ROI of Bitcoin investment over years is very great.
