I admire the attempt, once upon a time, that the USA did for government positions. It’s before my time really, but they put into place placement testing for many positions in the theory that only the best would rise.
But it was bypassed anyway and mostly gone by the 1980s. Still, whoever put it in place I respect. But the internal politics win every time.
It was flawed from the start in any case. But the heart was in the right place.
