The fact is poor people are needed by rich people. and the rich will even live in trouble without the presence of the poor in this world. because there are rich people because there are poor people.
Yes, I agree with you on this very statement of yours, as both the rich and the poor is needed to create balance in the world, because if everybody is rich, who will be the personal drivers, the cleaners and the security guards, and likewise if everybody is poor, who will be the employers, the directors and entrepreneurs, as all need one another for the society to function effectively.
I agree that poor people are not unruly class, in fact if we were to look into who hurts the economy of a nation more, we will realize that wealthy people hurt it multiple times more than what the poor does. Even if you consider poor people taking welfare and all, we have rich people stealing taxes, how? They just make it look like they haven't made as much by increasing their spending, and putting it on silly stuff.
Look at Nike alone, they have a different company that they use for licensing, and they pay that company a lot, to make it look like they haven't made that much, just one example. This is why poor are the unfortunate class that is getting the short end of the stick, whereas wealthy people are the main reason why economy sucks.
