So laziness do contribute to irresponsible gambling.
It's like they won't want to work and yet gambling isn't helping either, I guess this effect happened because they have tasted how it feel like to win some money through gambling so they shut every other doors.
If they are just going to rely on gambling to make a living, that's never going to happen. Gambling is a very expensive vice; you cannot be out of work and gamble.
Some addicted gamblers resort to a life of criminality to sustain their addiction, but to be lazy and still become addicted to gambling, I don't think you can last long without work; you need money to sustain playing in casinos.
