How can we possibly afford a universal basic income?
This appears to be the strongest argument against an income scheme. It also illustrates one of the basic problems in economic analysis.
When macroeconomic professors stand at the black board they generally draw an x-shaped graph and label one line to represent the real or physical part the economy and the other to represent the financial side. This is an important distinction because if one analyses economic problems only in financial terms the complexities of the financial system get in the way of clearly seeing problems. Too often economic problems are analyzed in financial terms.
In the case of the universal basic income the question should be are we capable of producing enough goods and services to provide everyone with the desired standard of living. The answer should determine the level of the basic income.
There are a number of economic issues with which we need to deal: we have extracted the most easily accessible energy and mineral resources and those left require a lot of energy to get; there are serious problems resulting from the fractional reserve way of creating money; the work ethic is a problem in a high technology world; and there is a need to recognize our economy, what we call capitalism, is based on legislation which restricts competition and allows some people to make profits they would otherwise not get.
I believe most of these need to dealt with at the same time. Certainly a UBI should be introduced at the same time as a reform of the financial system. These are complex emotional issues and will be extremely difficult to resolve.
The book Funny Money: Adapting to a Down Economy, by the author of this post discusses these issues. Please have a look at it.
