Funny thing is, nobody is asking the company he works for, just a broad stroke of the industry and what he does. Such as "I am in the vacation industry selling time shares". Which I knew a guy in the timeshare industry, you can absolutely make that in a good economy, no college degree in fact I don't think you need a high school diploma, you just need to be willing to bang phones and set up appointments. Lots of suckers out there.
Outside of time shares, I have never heard of an industry where some can quit multiple times and come back and a month later making $10,000 a month, at least legally.
