Farming was only created about 5000 years ago, but driving economics--even in the Primordial Rain Forest--was material goods and services acquisition. By about 1750 B.C., Code of Hammurabi was regulating interest rates. Moses was prohibiting Israel from charging interest rates amongst themselves: Maybe 300 years later.
Somewhere before that, humans had to develop a concept of number--1, two, many had become unworkable.
At the basis of it all is material goods and services acquisition, and slowly then distribution. Usury creates the first recognition that it is wrong to use it for distribution. By New Testament, The Greeks had become the math inventors, subsequent Babylon and Egypt: Moses had been one those, (Egyptian): Even according to New Testament Acts:7. Matthew 25:14-30, in fact shows the error of usury. The servants with the lesser Talents can't possibly keep up. So applied to distribution, it is lethal. Any currency units are insufficient for purchasing in any marketplace. Matthew 20:1-16, Applies an inverse of usury. Like the Obama-Biden, "Make Work Pay Refundable Income Tax Credit," The workers got paid an equal amount regardless if they had worked all the year, (more literally, "Day"), or not. So Purchasing Power was available for the market place.
Then anyone can create a rectangle with a left-right diagonal from the bottom to the top. The usury computing creates the upper right point, and the lower left point. Even rural Israel could spot a distribution problem, offered by some Carpenter's kid. Economics had even become visual. A line in the middle of the box, parallel to the right and left sides: Then shows the actual human distribution of goods and services in a community context.
Somewhere after the Ford Administration, even the Republicans could understand the visual. An equal amount per child tax credit was created to offset the problem of the regressive, (usury-computed), payroll tax. Being used to borrowing and investing: Even the concept of a "Total Credit Market" was being shown in U. S. National data and statistics. The numbers were astonishing, even in the 1960's.
In the rectangle, little dots parallel to the bottom and the top can be dotted or dashed in. Income raises happen. The source of the raises are the investments and spending, derived from the credit market. Anyone would not call it Socialist. The concept, "Market-Necessary" applies. Regulating Money Value is even in the US Constitution.
In the absence of the Matthew 20:1-16, distribution math: The lack of the purchasing power collapses any sense of a marketplace. "Market-Necessary" is a math-based description.
In the absence, therein comes the deficit financing. The Total Credit Market is about $71.0 tril. The federal deficit is about $22.0 tril. There are state and local deficits in governments worldwide, even everywhere(?). There are lots of forms of credit helping repay the investment credit that would otherwise no longer get repaid. Those kinds of credit tend to "balance," (offer repayment), of the usual investment credit.
So if the rectangle is to be believed, then Total Net Debt, (The credit market) should be about $36.0 tril. Total Personal Income is about $18.0 tril. Twice that is credit and credit balanced. Outside the box, then repayments of that tend not happen. Balancing credit starts to repay that.
For about two years--2008 to 2010--there was virtually zero increase of the total net debt, in the range of 53.5 tril., to $54.7 tril. Sixteen trillion dollars later is a bundle.
Mostly, there is a giant Macro balancing act gone haywire. If no one buys the deficit notes, or if they become too hyper-expensive. The indigenous peoples of the USA are rumored to have a word for the outcome: "It is a good day to die!"
Mainly Pochahontas had in mind an alternative. Senator Sanders and the Greening people are looking to Keynesian types of deficits. Social Liberal spending won't work. The basis arithmetic is bad. Even the Social Security COLA is usury computed. Eventually Richard Nixon signed on to Keynesian deficits, and then Reagan-Bush signed them into the reality: About that smart. Clinton won, and expanded the Republican Equal amount Tax Credit. That was mostly the only written recognition that I myself have that the federal government was coming to be on-track. At least some parts. Bush-Cheney tried Tax Cuts, failing to note that increasing numbers of filers already owed nothing.
Go back to Old Testament. The people had actually started praying to an arithmetic atrocity. There is no deity. Mohammed would mostly only detest riches derived from usury. No allusion to the New Testament arithmetic was noted. Karl Marx and Keynes made no note of it. Adam Smith failed to take any note of it.
Obama-Biden noticed that Tax Cuts problem, and made eligibility, "Refundable." At least someone possibly listened to Hillary, who went off instead to pitch (vote-rich(?)) Arizona. Speaker Pelosi at least does know about counting, for example. Former President Bill had already become publically alarmed.
In the context of visuals(?), Pochahontas could be said to have become Aunt Jemimah: In a Rev. Martin Luther King, Jr. Motif. Many still look at visuals: Unless they are presenters at Academy Awards(?). The outcome of the adaptation of Matthew 20:1-16 method: Is that everybody filing would get something to spend. Taxes would be paid with basis in a thriving marketplace.
The Republicans took that away, and most recently went back to failed neo-Keynesian tax cuts. Even J Kenneth Galbraith had published that Reagan-Bush were not Keynesian tax cuts.

(Clearly: Teaching is not possible at any grade level, without the doctoral degree--unless it is believed that some kids are better than other kids, and that all those other kids are not worth the extra effort. That should at least be a description of school, or something clearly market unfriendly! Anyone notices how adults treat their offspring, anything loving of them tossed aside! Mostly little kids are clearly thought pond scum!)
