If a business fails then the employees are at risk of losing everything if they can't pay mortgages/rent etc. Yes, they might be able to go and get another job but that goes for the owner as well. Employees, whether they admit it or not are invested in the success of their employer.
I don’t think anyone is arguing against that, but at present it’s clear that inequality is hurting demand. Employers may have the vision and the strategy, but they still rely on their employees to get the job done. And if their employees wages are too low, they can’t then go out and spend in the economy.
The relationship done well is symbiotic, too much of our current regime is parasitic, with all the benefit accruing to the employer, and the employee in lower wage situations barely meeting their basic needs, even with the employer’s low wages being subsidised by the taxpayer in the form of Universal Credit.
