If top 10% of people create half of all spending and more of the spending on nonessentials, thus feeding majority of economy/creating majority of value, things will revolve around them. Something has to be done so that the other 90% won't be trying to break things down just for the sake of it. It's also that top 3% pay half of all federal taxes. Can we expect that the government will really care about others? It's also that same top 3% have a net worth of $5-6M and up - in the "never have to work again unless it's real fun" range.
If the majority of government funding and good half of corporate value comes from people who don't care anymore because they have arrived, can we expect anyone to be a responsible voter? We are firmly in 'bread and circuses' area.
