"To met the requirements of justice and equity, every effort must be made, while respecting the rights of individuals and national characteristics, to put an end as soon as possible to the immense economic inequalities which exist in the world..."-GS 66
It is evident that despite a global economy, industrialization of resources, and effective means of distribution to every corner of the planet, there still exists terrible discrepancies in wealth and living conditions. If America's finest products can be delivered to Japan and Germany, then why not Africa and the Caribbean as well? It is a matter of money and financial security, everyone would rather be well off than broke, so we overcompensate. The will to act is inhibited by the fear of becoming destitute ourselves.
The consequence of a universal, but fragmented Church means that it can only influence rather than control the governments which possess the capabilities to end indecent living conditions. Therefore, it should be made clear that the Church does not align itself with a particular form of government, but instead will act according to Tradition:
The language of Gaudium et Spes and even recent remarks by Pope Francis seem to suggest the Church might be against governments that favor capitalism, instead favoring a socialist type government that would at least meet the needs of each citizen. BUT this conclusion is far too simple...

"Reforms are called for in these difficult situations: incomes must be raised, working conditions improved, security in employment assured, and personal incentives to work encouraged; insufficiently cultivated estates should be divided up and given to those who will be able to make them productive."-GS 71
Is the Church socialist? No. The teachings of the Church coincide and contradict with every sort of political creed. The Church supports the protection of basic human rights and works towards improving the dignity of every human being. Thus, on occasion, the Church seems to be aligned with political parties that favor government organized charities and health programs, but the Church might also oppose those parties if those programs diminished human dignity. For instance, an ideal form of universal healthcare (meaning every person could be taken care of with little to no expense) would be great! But such as form has not been created, and is unlikely to ever be created (for healthcare requires the manpower of physicians, nurses, and technicians as well as medical supplies and research. Those people deserve proper compensation to provide for their families and communities as well!). Therefore, the Church relies on the charity of individuals, encouraging each person, lowly or otherwise, to contribute within their capabilities.
Those who can do more are called to do more! A CEO can organize a large-scale relief mission whereas a modest auto repair shop owner is unable. It is the mission of the Church to evangelize those with resources and talents to support those with less. Still sound like Socialism? Maybe, but charity and mandatory taxes are distinguishable, and this reflects the content of the giver's soul.
