Well, you do realize that a Socialist Government (different from a Communist Government) would have still probably used outside resources such as companies to help, but chances are, the government would have aided them for free, without worrying about the cost. Futhermore, in the CCC Paragraph 2425, it states this:
"The Church has rejected the totalitarian and atheistic ideologies associated in modem times with “communism” or “socialism.” She has likewise refused to accept, in the practice of “capitalism,” individualism and the absolute primacy of the law of the marketplace over human labor.206 Regulating the economy solely by centralized planning perverts the basis of social bonds; regulating it solely by the law of the marketplace fails social justice, for "there are many human needs which cannot be satisfied by the market.“207 Reasonable regulation of the marketplace and economic initiatives, in keeping with a just hierarchy of values and a view to the common good, is to be commended.”
This paragraph perfectly fits what I believe to be true, and ultimately, that we need a Mixed Economy, which means Government Involvement (regulation-which puts the government on the left of the economic and political scale, closer to Socialism) and it rejects pure Capitalism, as some on the Forums would have it. It’s not “Let’s flip a coin and be Communist or Capitalist, or Communist and Fascist (Communism involving both political and economic ideologies, therefore belongs on both spectrums)”, but it’s that we need a balance of both. This is the idea behind Democratic Socialism, which is a Democratic Government which regulates the economy.
So, in actuality, “Capitalism” did not save the miners, because you can still have the same effect with a socialistic principle. The only difference is that as we let the companies make the technology that helps save the miners, the government regulates the economy so that the companies don’t leave an economic mess when the miners return home. Because when you state Capitalism, I’m sure you mean the Capitalism without any Government involvement, or the one with as little as possible, correct?
