Actually, unemployment insurance does not "pay someone to not work" either hypothetically, in implementation, or in factual outcome.
I believe you if you say that you would sit around doing nothing while collecting unpemloyment insurance and lying to the employment development department. Beyond that, you have created a fantacy with no basis in reality.
Also, all demand and supply, all of the money supply, all economic output exists because of borrowing. Every single dollar in the economy exists because it was borrowed. Every dollar is exactly accounted for by debt.
So saying "Artificially bolstering demand through debt" is completely meaningless on the outset because there is no "not debt".
Ok, I'll be more clear. Artificially bolstering demand through net increases in liabilities is unsustainable.
I get that you would like to use the implied subtext of "artificial" to attach a sense of "it is bad" but there is no merit to it. The money supply is "artificial". There is no such distinction as "natural" vs "artificial" here. There is no thing as "artificially bolstering demand". The stimulation of economic output is, in fact, sustainable. All liabilities in the economy are exactly matched by assets.
It sounds all great, this "artificial boltering of demand" but that is as far as it goes. The reality of the money supply is that it is all created from a liability which is exactly matched to an asset.
The reality is that there is no general distinction between what economic agent does the borrowing, whether it be gov't, households, or firms as long as the result is that of increasing employment amd output. The entire money supply is simply an artificial, man made tool, that increases the efficiency of economic transactions.
The difference between a GDP of $10 trillion and a GDP of $11 trillion is $1 trillion in additional money supply, consumption, income, production and the additional individuals who are working, receiving the income, producing the goods, and consuming the goods. It is entirely sustainable. How the economy gets there is irrelevant.
Once one more person is making the stuff that one more person consumes and the money supply has increased to the amount of money that accounts for that one more yearly income and consumption then it is physically indistinguishable from any other one more person working and consuming. As well, as the one more sum of money that accounts for that one more basket of goods and one more income are borrowed regardles of whether it is the govt, households, or firms doing the borrowing, how that additional money comes about is entirely irrelevant as it is physically indistinguishable from any other money.
The fundamental difference between a good economy and a bad economy is in the employment level. What is physically distinguishable is the difference between an individual working and producing as opposed to an individual not working and producing.
The money is simply an artificial tool that is used to measure the labor hours spent. In fact, in the final analysis, that is all it accounts for, labor hours. The labor hours are the real, natural thing. The money is an artificial tool.
