Why would they? That means they would have to charge you less, and make less profit off you. I think it's safe to say that business, especially in america, is all about profits, at ANY cost. Do you think a big pharma company would not kill you in a NY minute if they stood to make a $billion off the drug that did it? They do that every day.
Business, especially in America, is all about maximizing shareholder value.
You don't maximize shareholder value by killing people. That billion dollar "profit" would be destroyed by lawsuits, bad PR and tanking stock price.
BTW... For the life of me, I don't understand how the word "profit" became an obscenity.
The business of America is business. Business--and the Crown's attempt to wrest control of American business--is the whole reason we fought the Revolutionary War.
