No. Even people who work for themselves need to be good enough at the job to have people use them not somebody else, ie hard to replace. And a lot of folks who work for themselves their services make other people money, people on the PGA tour are self employed, and the tour makes a lot more money on their efforts than they do.
Hmm, so I buy properties at foreclosure, repair them, and sell them. I may hire some vendors, but the vendors cannot hire or fire me. When I buy the property, that is a raw material, and in most cases, the bank is not making money off me ... they are at foreclosure for a reason. There may be a couple of charges for processing the transaction, but they are trivial for the most part. When flipping the property, I determine what I am going to do, where I will buy my materials, who I will use as contractors, if any, and negotiate the prices. When I sell the property, I may pay a real estate commission, but again, I can hire and fire my agent, chose the escrow company, etc. Nobody is profiting more off my deal than I am, and they only profit off of my deal if I allow them to. Nobody has the ability to “replace” me. Period. However, I can replace them. Once I buy the property, it is mine to do with as I see fit. I am not beholden to making money for anyone other than myself.
