In my view, wages are the backbone an economy. If workers have difficulty finding a job, or have difficulty earning sufficient wages, the lack of wages will be a problem, not just for the workers, but for governments and businesses. Governments will have a hard time collecting enough taxes, and businesses will have a hard time finding enough customers. There can be business-to-business transactions, but ultimately somewhere “downstream,” businesses need wage-earning customers who can afford to pay for goods and services. Even if a business produces a resource that is in very high demand, such as oil, it still needs wage-earning customers either to buy the resource directly (for example, as gasoline), or to buy the resource indirectly (for example, as food which uses oil in production and transport).
It is not just any wages that are important. It is the wages paid by private companies (rather than governments) that are important, as the backbone to the economy. Governments tend to get their revenues from private citizens and from businesses, both of which are dependent on wages of private citizens. There are a few pieces outside of this loop, such as taxes on imports from foreign countries. With the advent of free international trade, this source is disappearing. Another piece outside the US wage-loop is taxes on resource extraction, if these resources are exported.
Instead of using the analogy of a backbone, perhaps I should say that wages are the base that ultimately determines the quantity of goods and services an economy can afford.
