つpork barrel
As far as I know, we, Japan or the US, love pork after all.
Some systems such as political appointee seem fair, but it also has advantage as well as disadvantage.
An Asian, not naturalized one, public servant sued the ultra-racist governor claiming that she wants to be promoted. Of course, she could if she is just naturalized like her brother.
Unfortunately so far, no great oath in the naturalization like in the US, so it is not that unfair system for a foreign national who want to work in a public sector.
