People who support their faimiler through full-time jobs are lazy? I guess you've never met the benefit kings/queens and full-time alcoholics that live in my neighborhood. That would've calibrated your laziness meter.
Others are honorable and work (at least intermittently) to support their addiction. One guy is an oceanic ship captain, who work fixed-term contracts, and is 100% sober during them (one infraction would end his career). But, once he's back from the contract, he stops on the first gas station on route from the port to his home, buys a bottle of vodka and drinks it on the spot. This shows that controlling alcoholism is partially a matter of willpower and motivation.
