> what's stopping all those people you fired from starting new law companies

This is beyond naive. We've got plenty of successful businesses in front of our eyes, what makes any of us work for them instead of starting competition? Maybe lack of appetite for risk, lack of means to take on some substantial amount of it, lack of perfect timing, bills, children and parents to support, accumulated momentum in another profession and no skills to run a business, no meaningful connections?

The list goes on and on and to think you could just start a business regardless of your circumstances, and even more so, try to make this hypothetical sound as an answer to the very real issue of increasing job insecurity is just pure malice.
