"With adequate profit, capital is very bold. A certain 10% [profit] will ensure its employment anywhere; 20% certain will produce eagerness; 50%, positive audacity; 100% will make it ready to trample on all human laws; 300%, and there is not a crime at which it will scruple, nor a risk it will not run, even to the chance of its owner being hanged." - Karl Marx
Unprofitable business will not exist.
Profitable but unethical or illegal business will stay.
