The USG is already putting tariffs on foreign planes. We have all the downsides of nationalization without any of the benefits of collective ownership (except for the fact that Boeing is in people's retirement accounts, which is a little collective ownership). Capitalism and socialism on their own both have provisions for taking care of the elite and taking care of the average person. What we have now with these pseudonational industries is a combination of both that takes the elite-benefiting parts of capitalism and combines them with the elite-benefiting parts of socialism.
"The World Trade Organization said on Thursday the United States had ignored its request to halt a subsidized tax break for Boeing Co in its main plane-making state of Washington as a 15-year-old transatlantic trade row edges towards tit-for-tat sanctions."
It's funny how the US complains about China propping up or even owning (usually partially) big corporations there, but they do the same with Boeing and many other companies.
At least in China, the government is the one that has the final say on everything, and the state-owned corporations have to do what the government wants. Here, the corporations get to do what they want, but they still get subsidies from the government but without being required to operate in the interests of the government or the nation at large.
