The wealth distribution is remarkably skewed. Today it might not mean anything but give it a few years of people having no money yet having bills, loans, mortgages, etc. to pay with no possibility of retirement and you have yourself a prime situation for another French revolution or oppressive police state.
It's not something that you can just let sit, it's going to get bloody if it is not addressed soon. We have seen this everytime in history. It is not possible to sustain such levels of income inequality.
