"Shareholders" are often people who invested in fonds which invested in fonds and they are thus several steps of separation from the final invested corporation. They only want their pensions to be stable, and de-facto own tiny slivers of hundreds of corporations, maybe not even exactly knowing which ones.
That detaches them mentally from those corporations, much like when you go to a restaurant and eat the food without being particularly bothered whether the cilantro in your soup, supplied by a large-scale supplier and imported from another country, didn't originate in conditions worse than typical for that developing country.
Modern civilization is so complex that if you wanted to check conditions of every vendor of everything you consume, you'd simply not have enough time and energy to do so.
I am typing this on a Dell laptop; should I be particularly interested in what happens in every Dell supplier which contributed to building of that laptop? Are you? I just bought it and started working on it; we may certainly call this "complete disregard".
I never said anything about obligation. Of course they’re not obliged to provide extra jobs, but it is a moral obligation to treat those whom you employ with dignity. I would love to understand what you actually define as a moral obligation considering your vacuous response.
