26 Billioneers own as much as poorest 50%(3.8 billion people).

So Oxfam reported that 26 super rich people own as many assets as 3.8 billion people who make up the poorest half of the world's population.

Would this be because they avoid taxes and pay employees as little as possible?

Is this sustainable, is it moral?

It seems these world financial crashes are very good news for the filthy rich who are becoming filthier.
