> The US does something similar with the national defense manufacturers.

You also see this with the European space industry especially in the rocket building. A lot of money is poured into the industry even if there are no massive returns or advancements just in order to keep the people and skills. If you let these slip, rebooting the sector would be a decades long affair so doing busy work sometimes is the better option.

Heck, even most large tech companies do this type of busy work assignment. They hire en-masse but many of those people are never really put to work. Their greatest value is that they stay out of the competition's hands, if there is a massive project coming up the people are already there, and they can be dumped in case of emergency to prop up the stick price.
