DOGE couldn't have possibly worked, ever. I think everybody knows a situation where there's an employee who is contributing far more than their own manager knows. So the point is that even if you asked everybody's immediate managers to decide who to lay off, you'd have huge mistakes being made.
A central bureaucracy like DOGE is so much farther removed from that situation that it's not even funny. There is simply no way that it has the expertise to conduct layoffs, and it was obvious from the beginning. Companies facing layoffs know that they will lose unreplaceable employees, but they have to do so due to immediate financial pressures, nothing like what the government faces.
So, DOGE was either a stupid idea created by absolute morons, or it was a cover for bad actors who never intended to do what they claimed. Or a little from column a, and a little from column b.
