The US government does not currently have a democratic mandate to operate as the social welfare state. Consequently hundreds of thousands - if not millions - of people are immorally (by my own standards) disadvantaged and with no means or realistic opportunity to better themselves.
So if a private company (or shareholders-forbid: a publicly traded company)’s leadership feels a moral obligation to help those left behind by the state - more power to them.
Until the US truly embraces the “for the people” part of the “by the people, of the people, for the people” part of their unofficial motto it really is up to private entities to make-up the difference.
[1] UPDATE: To clarify - I don't mean that I somehow know what's in someone else's best interests - because I don't - nor their exact reasons for voting for a particular party or candidate - but I mean that it's still possible to _objectively_ say that many people vote for ideological or sentimental reasons that appeal to them (which is part of democracy!) with - or without - having done (for example) a spreadsheet comparisons of how each candidate's manifesto politics would affect their cost of living, quality of living, economic expectations, and so on. I can respect someone voting against their interests for ideological or moral reasons - provided it's done with informed consent. I'm not convinced that most- or even a plurality - of GOP voters in recent US elections sat down and made a spreadsheet and said "yup - I'm okay with rising the cost of my individual health insurance provided it means I have the choice to refuse healthcare coverage" (and that is not a misrepresentation of the ACA and its opponents' stated positions).
So by all means - vote against your own interests - provided you do it with informed consent - otherwise you _really_ are voting against your own interests.
