Improving an employees life is exactly how capitalist systems work. It’s a competitive market. An employer can attract top talent with low attrition by keeping employees happy. This is very beneficial to a business.

Unhappy employee = low output and/or attrition = bad profit

Since it’s such a capitalist market this “unhappy employee” can search for an employer that would make them more “happy”. Employers will then improve happiness of employees to attract this “unhappy employee” so he’ll leave his current company.
