It could also be argued that by maximising profit and shareholder value, companies are screwing workers over.
Both directly, in the form of remuneration / benefits / working conditions, and indirectly, in the form of tax optimisation, pollution and legislative lobbying.
It is true that most very wealthy people make their money from dividends and rent, rather than wages. So this is actually 'unearned' income.
It could also be argued that by maximising profit and shareholder value, companies are screwing workers over. Amazon is an example.
I may be totally off track though.
