It's found in most humans most of the time.
Maybe not in business but in wanting more or the best. Unions want more for the workers (Themselves). If they were so anti they would be out demanding more donations given to charity and leave the wage rise so it can be sent to bangladesh. Do we see that? no, but i bet you want more cash so you can buy a better car or a good stereo.
It is human nature to want more. It's just that some are better at getting it.
