Running a business in a way that hurts a great many fellow Americans?...
you're not thinking about this objectively. what these businesses are doing are not actually hurting anybody.. they just aren't helping anyone in particular either.
the principle you're missing is that workers think they have a right to depend on a private corporation for their livelihood. they don't. workers have a right to sell their labor for a wage to anyone they want. corporations also have a right to offer a wage for a certain amount of labor. both parties here have a right to deny or terminate business at any time they please.
no company, no matter how large or small, exists to provide a job or income for the labor force. it exists to make profits for the owners. sure, it doesn't sound 'nice' but it's no more immoral than asking a worker to work for free and getting upset when that doesn't happen. it's business no matter who is crying about fairness to weasel out the outcome they desire.
