In economics perfect markets mean that your company that raises spherical cows has no moat against others doing the same. If you do something to gain profits to become rich someone else joins the market to compete those profits down to zero. This reduces inefficiency and makes everyone rich.

Deregulation is sold as getting closer to this, in reality it means the money collects wherever the market breaks down, monopolies, network effects, externalities, concentrated special interests, middlemen, oligarchies, gangsters, landlords etc.
