What makes you think that they care about the working class or lower classes? All they care about is themselves and their companies and businesses.

A rich businessman would be smart enough to understand that the more he shows care and affection for the working class and lower classes, the more good and productive workers he and his companies will attract, and that means more revenue for him in the long run. I'm not saying this is the case with every rich person, but it is for the most.

What does a person working for a company need? A respectful work environment, and necessary basic requirements, and a person running a company or a business would know what he needs to do to keep their workers loyal to the company because that brings more productivity, hence more growth for the company.

So the point is, that the rich are more smart than they are affectionate.
