If it doesn’t make logical sense but it happens, that means you are making incorrect assumptions about the world. Capitalism is very capable of creating commons that help its power structure, like public highway systems, the global positioning system, or the 2008 bailouts. Having the continued habitability of the Earth depend on maintenance that only US megacorporations can perform is appealing to the US upper class. Theough a Marxist lens, this is no stranger than workers going on strike and calling for a general strike. These investors are hoping to get their money back through capital class solidarity, likely in the form of massive investment and big government contracts.
