What makes you say that?
Just projecting his own personal fantasy. Arnold was never poor. He already owned his own gym by the time he was 19 years olds, financed by Weider to promote his products and magazine, and ran his own business (mail order, construction, seminars, guest posing, real estate). According to a bio on Arnold written by an embittered Lesbian trashing him, said that he was already making six figures in his early twenties. Good money now, and a ton of money back then.
Many open and closet gays can't keep their phaggot fantasies to themselves and discount that Arnold had no need to suck cock or bend over for a schmoe. He was a gifted businessman and self-promoter from the get-go and a money-making machine.
Both Arnold and Franco were supremely disciplined, hard-working, and motivated and saw the opportunities in America as a gold mine. At the time they were the only two bodybuilders that didn't need to work a regular job and supported themselves as entrepreneurs stemming from their bodybuilding endeavors.
