Historically, there have been three branches of government:
If we view society as a family and the government as the parents , then the legislative and executive are the father , while the judicial is the mother . The former requires wisdom and intellect, while the latter requires love and conscience. As you can see, the father branches of the government outweigh the mother branch and so, although there might be legal justice, there is little avenue for political or economic justice. This is seen in the election of corrupt officials and in the presence of economic inequalities.
To complete the proper system of government, we propose a fourth branch, called the Resource branch. This will mimic the role of a housewife in budgeting the family's expenses and in noting down the needs and condition of each child, which represents each citizen or group of citizens. At the moment, such responsibilities are done by the Audit department of governments, usually as a separate commission, which merely acts as an appendage instead of being an equal to the three branches.
While the executive's expertise is physical action, and while the legislative's expertise is debate and legal experience, the resource branch's expertise is inspection and aggregation of real data and its real-world presence. Its main duties will be:
Implements laws, runs the army
Tries cases according to the law
It takes away some of the motherly duties such as caring for the poor and arranging for the logistics of supplies, away from the father, or the executive, so that the father can focus on more important things. Like all branches, this branch is independent. But while the executive and legislative are elected, the manpower for the judicial and resource branches are sourced from law schools and accounting or econometrics schools.
In the current system, the legislature creates a new tax, which will be collected by the executive, with tax cases to be tried by the judiciary. In the proposed system, the legislature creates a new tax, but coordinates with the resource branch on how and where it will be extracted from, together with projections on its effects. The ironed-out plan will then be sent to the executive for implementation.
As a historical example, let us put ourselves in the American Revolution in 1777 at Valley Forge where George Washington (executive branch), could not get food for his troops because the expertise of Congress (legislative branch) was lawmaking and not logistics. A resource branch of government would've mapped the resources available in the colonies in advance and then relay the information to the executive for collection. Any injustice committed would then be tried by the judicial branch.
The idea for this branch came up while planning out the implementation of our new economic system in an actual society. Since we don't have much manpower, we tried to automate, or at least make the system automate-able in the future. The resources needed to run the system have to be used as efficiently as possible without an expensive adminstrative system. Thus, the idea for an automate-able resource branch came about, which will have its genesis as the resource banking system used to safeguard all transactions. This is in line with both the vision of economic singularity and David Hume's ideal commonwealth
