I reverse this question to you, what is the solution? I have none but asking companies to change will do nothing. Forcing them to change is a dictatorship. So you tell me what the solution is?
1. Set the example by creating or joining organizations that are not based on Capital owning the majority of the organization (cooperatives, non-stock not-for profit etc..)
2. Increase taxes on non-labor capital growth to directly fund full employment programs Eg make "profit" impossible
