No one ever, ever, ever, did things 'all themselves'.
That's a very simplistic way of looking at taxing, company ownership, 'wealth creation' (for what that is worth), & so on.
my brother did. in 1973 he was working for the MEB he resigned and took out a loan to hire an Articulated Lorry and Driver, covered the costs himself and brought back about a million candles and then sold them to the co-op woollies and the rest.
Mom went ballistic , Dad said well done son, He bought a house, a new car and never really had to work again. But he did.
