you can totally be on disability for one specific job but working a different job.... if you do it right and do not keep it secret.

if you work in construction and your spine goes bad, you may be actually and legally unable to do the job. but you can still do stuff in front of the PC and over the phone.

here we need details, snake keeping is quite forgiving meaning you can work slowly at your own pace. we dont know, and i know foxnews cannot be trusted with anything, not even the weather report. something like multiple sclerosis or heart disease can easily knock you out of many stressful or physically demanding 8-to-5 jobs while keeping you able to work different jobs. Thats why i didnt mention that, insufficient information to even speculate. Sometimes a health problem legitimately causes insurances to trigger and to pay out and the person is forced to take on a different job and ends up earning more there, and there is nothing illegal about it.

for me the core problem is that he did not have a company or business registered while running an operation with significant cashflow. if his snakes are really worth 500000 dollars (based on foxnews, who do make stuff up) and he did not own a company and is not CEO, thats a real problem with bookkeeping, taxes and so on.
