Socialism is when means of production, such as factories and banks, are owned by political entities. Taxation, regulation and tariffs are of course something similar because they allow political entities to influence the private sector, but they fall short of ownership. In other words, either we never had anything other than socialism in 20c industrialized world, because we never had capitalism free from taxation, regulation, and tariffs, or what the Pope is proposing is a development that is in line with 20c regulated and taxed capitalism. The pope is no revolutionary.
The Pope actually is not saying that anyone should be mandated beyond what he already in justice owes. So his proposal is not event tendentiously socialist. If you don’t see injustice in the two examples that I gave, then you don’t understand justice.
It is the Catholic teaching that human dignity and life is something we owe others. So if the operation of the market deprives someone of his dignity or life then that operation of the market is unjust. Whether or not you see that principle reflected in the story of Dives and Lazarus is a matter of interpreting the Bible differently, doesn’t change anything in the grand scheme of things. The Pope is Catholic and he clarifies the Catholic doctrines for us, not any other kind of doctrines.
So, how is taking monies from some people to give to others not wrong? Do you realize there will always be people who are more poor than others and that taking from the rich to give to the poor doesn't do anything but create another injustice?
In any occasion someone buys something that someone sells, both parties believe they are getting the better end of the deal. That market is operating justly, no matter what the long-term repercussions might be to one or the other parties.
It is not moral before God to make someone give something they do not choose to give. Do you not believe that God knows our hearts and will judge us one day? Forcing someone to give against their will to another does not make that transaction, nor the person being coerced, righteous or just in any way. Can you not see that it is you and the Pope, with your views on this, that truly deprives people of “their dignity or life”?
The whole “Robin Hood” lore is romantic, but grossly unjust. It is wrong to steal, no matter what your intentions are with the ill-gotten goods.
