Regardless of what you think of the Bush family, there is no doubt they believe in noblesse oblige and the value of public service. It is much to their credit.
Trump, on the other hand, has no concept of public service. He doesn’t see himself as anyone’s servant. To him, winning an election is an exercise in ego gratification, and the presidency is a prize, not a job. As a result, he has no reason to care about the American people; it’s all about him, not us.
If you wanted to put everything that is obnoxious about the Trump Administration in one nutshell, you could do worse than that.
