The definition of a healthy economy which has been adopted by the West, and imposed globally, means an economy that serves the interests of the richest people. It means an economy that is good for major corporations and their shareholders. There is no reason why we must accept this definition.
You can organize your economy any way you like. You can allocate your national budget as you please. You can implement tax policies according to your own understanding of what will benefit the society. You do not have to follow policies exclusively that maximize profit for the riches segment of the population. In real economics, that is bad policy.
In real economics, you need people to have money, to circulate currency in the market; you need people to be paid wages that are sufficient for their needs, and which allow them to also be active consumers.
The super-rich do not contribute to the economy. A man with a million extra dollars does not spend in the market what a million people with one extra dollar spend. his money goes into shares of companies, or into his bank account, or into investment funds, or perhaps to a few luxury items. The wealth of the super-rich does not circulate in the market. That is money that accumulates, not circulates. It is bad economics.
Higher wages are good for the economy, but bad for corporate shareholders’ dividends. But there is no reason why corporate shareholders need to be the only segment of society whose interests are served.
