I can tell you this, depending on what your doing there is benefit to it.
Being able to be employed and "outsource" your job to someone else is a for sure plus. I can see this working in Internet marketing, but not most other jobs. I once had a job before years ago where I was hired as the Internet marketing guy where 90% of my job was SEO. My employer didn't know this, but I just ended up hiring out odd jobs to people on Wickedfire and also got a VA for $300 a month who I made do most of the SEO shit.
From time to time I would need to send out an email or do some PPC shit, but other then that, about 18 days out of a 20 day work month I spent playing poker online, building up MFA sites, and learning about affiliate marketing while pulling in a $90k a salary from my employer. What I did was no different then how a lot of guys here arbitrage PPC, CPA , or service offers, I just did with my job.
Spend $400-$500 a month on a PPC campaign, make $2000 back ( but face getting banned, doing cloaking, shaving, scrubbing, etc on affiliate offers, hosting going down, etc ) OR spend $400-$500 a month and make $5000 a month in salary ( but have to deal with driving to work, listening to a boss yap his jaws, 1 hour lunch, etc ). With some of these jobs at least you count on pretty much making your salary for months ( unless your a fuck up and get fired ).
I see no difference in this then having:
a client
a steady ppc/cpa campaign
If your doing some other jobs though where you cant do the above.. then FUCK NO, I WOULD NOT GO BACK TO ONE.
