There's always going to be a lot of money/profit in amoral behavior that's legal -- while being moral means passing on that behavior and money. It's possible to run a business morally and successfully, but rarely as successfully as someone who runs one amorally.

IME, most people in the US will happily take a job with the extra money at an amoral company, even if the lesser paying job at a moral company would still be enough for a comfortable life. (Folks in the US are very price conscious; I don't know how that compares to other cultures/ societies.)
