I answered why having a team is beneficial to me #2855. As I said there's a big difference between an all-around AP vs. a specialized sports AP.
When you have employees you are the one putting up the money and you are making a majority of the profits. A tout/investment recruiter with integrity should be passing on most of the profits to his investors.
There are so many different roles an employee can take so there is no simple answer. Employees can be used to simply speed up the process and improve your hourly. For example, there might be a multi-bank of machines with a super high progressive. It's best to be able to lock up those machines so you are assured to capture all the value(such as the meter movement). Let's say there are 4 machines and the total value is 100k over a 40 hours cycle. If you only have 3 of those machines and an outsider has one, you give up 25k in value. If I can pay someone a fraction of that 25k it's more than worthwhile since they are the ones putting in the time. But let's say I decided I wanted to take on investors give them a majority the profits and put the time in myself. That would be a terrible deal for me since I would be putting in the same amount of time and making a fraction of the value.
