Well, it depends on what "richer" means, and how "richer" operates. The Russian Military Industrial Complex, for example, operates on a nationalistic, rather than a capitalistic basis.

Rostec, the giant Russian military industrial behemoth, is comprised of 800 different enterprises, producing everything from drone technology and EW systems to tanks and armour.

It is, however, state owned. That means that the money the Russian state invests in Rostec goes into production.

The US, on the other hand, has a Military Industrial Complex that is 100% privatised. The companies in the American MIC do not have the defense of the United States as their primary operating directive. Rather, these companies exist primarily to deliver profits to shareholders.

And they are some of the most profitable companies in the world.

That is why the US can spend almost a billion dollars a year on "defense" and still not have enough spare parts or ammunition. Producing 155mm shells is a boring, low-profit enterprise. It's much more profitable to develop expensive new systems like the F-35.

Moreover, delivering "results" is not in the MIC's interest, as long as the money keeps flowing.

Maybe that is why the US still does not have a hypersonic missile to compare with those of Russia and China.

The US's "Dark Eagle" hypersonic missile has been delayed and delayed, all the while sucking up hundreds of millions in R&D and other expenses. The expected unit cost of the Dark Eagle, once it goes into production) is $41 million, whereas the Russian Kinzahl costs only $10 million.
