TNG is a fine example of "competency porn", where everyone knows what they're doing and usually makes the best available choices. In today's world, that's even more compelling than it used to be.
It's also because the world in TNG was not centered around amassing the biggest pile of money.
Extrapolate from that and it becomes a easier to make the right decisions.
That's just what the writers of the fictional show thought was utopian. It doesn't tell us anything about the real world; it's fiction.
I mean, it was the flagship starship of the fleet. So yeah, it better be staffed with competent people like that.
