The rich do not create jobs in the same way that ordinary consumers do. More equal societies create more jobs, because more people have relatively more money. More unequal societies create fewer jobs because most people can’t afford to buy more than the basics. Jobs are a consequence of a feedback loop between consumers and suppliers. Higher taxes need to be collectible through internationally applicable legislation that does not allow the super-rich to salt money away in tax havens.
A more equal society is a fairer society, but only if the super rich are not able to escape a globally applicable tax system.
