Looks like Bernie Sanders is catching up on Hillary.
He is pushing for more equality of wealth as I understand it. The US rich have so much they must run out of things to buy.
Bernie Sanders will not be the democratic candidate, not because he will not be able to catch up to her, but because the DNC has veto power. If Hillary maintains her lead, the DNC will say "we chose the people's choice". If Bernie Sanders surpasses Hillary in the polls, the DNC will still choose her and say "we chose the candidate with best chance of winning against the Republicans". Bernie Sanders does not have enough influence and he is too socialist. Socialism is on its way out.
The US rich have so much they must run out of things to buy.
The Democratic senators are just as rich as the Republican senators. Neither of them are going to do anything that will jeopardize their incomes. Senators are allowed to increase the pay for the next incoming senator, so if they get reelected, they have essentially increased their own salary.
The wealthy never run out of things to buy. They just create designer services. There is a service that you pay $150,000/year for and they send you gift wrapped presents throughout the year. The presents that they send you do not add up to $150,000 at the end of the year. It is just so that you can say you belong.
I have a neighbour who charges people $1,000 to decorate people's Christmas trees.
Pelican Hill membership dues are $22,000/year.
I do not know if this is a global trend, but two theatres by me service you Champagnes, wines and dinner while you watch movies in very comfortable digs. That reminds me. Movie tickets are becoming increasingly expensive.
