This would be a socialist government.
The main goal of having a socialist government, is to evenly distribute goods and money and to have everybody be treated as fair as possible. If you classify as a socialist, it is kind of a broad term. Many socialists believe in different things, but having everyone equal and treated fairly is usually the main belief.
With socialists governments, taxes are very high most of the time, so the government can afford to produce more goods for the people.

Plus, it was much easier for all 13 former colonies to accept the Articles of Confederation than the Constitution because it basically just handed the states governmental power and told them to cooperate with all of the other states. The Constitution, however, sought to take away some of the powers they had received such as the ability to regulate their own taxes. Understandably, it would be much more difficult to get a unanimous vote for for the Constitution due to this so the 9/13 rule seemed more reasonable.
(even though the Constitution ultimately ended up getting ratified unanimously)
