This is not the case under capitalism, it happens under regulated economies.
Under capitalism, "profitable" _is_ the signal of the net value something generates, and that is its own motive.
> It's simply never enough (hence the many references to unrealistic infinite growth),
Untrue. Many people and companies operate under steady (or even declining) profits, still run while they generate profit.

A great number of good options for valuable companies and products and services are available under capitalism yes, this is one point I will agree on.
