I would tend to agree that too many people think they are entitled to something, something to do with Modern culture we are given so much. I think this is this is the reason for movements such as this, but in reality it is true that the world doesn't owe you anything if you would have asked people that question 500 years ago, they would say that you owed this world or God something rather than anyone owing you anything personally. I believe this tends to show how spoiled humans have become as a species to think that the World owes them something that is false. Tomorrow a super advanced species could come take from you everything you own, all this to say even greater some people think that the universe owes them something it doesn't either.
There's little doubt about the reason why the right in America consider that they're not entitled to anything. They're promoting the American way of the government not being responsible to the people to give them rights and freedoms, etc. The American right has been schooled to see that as their own responsibility to construct for themselves and then claim.
This justifies the notion in their minds that the wealthy justly earned all they have in America. It's meant to continually put down any ideas of the system being fixed to give more and more leg up for the wealthy..
It appears that the political left has at least started the ball rolling on the fact of the huge and growing income inequality under Trump. All it calls for is for ordinary Americans to escape from their brainwashed condition. Have you noticed that all the Dem hopefuls have the same idea on that?
Let's see if they can be convinced to sh-t in their own nests again by calling all those hopefuls communists?
