Any time someone has bad luck, (like say a layoff, and as a result someone else takes advantage, and throws them out on the street (Like say, a bank), and the response is "It's just business".
Like making a buck by any means necessary justifies anything?
In that case, slavery was "just business" too. By the law of the land at the time, it was their bad luck being black. Not your fault for making money off them, it's just business.
And here's where you point out there's a world of difference between someones race, and losing a job. Of course there is. That doesn't make it right, for someone to take advantage of someone else's bad luck for profit. That's a choice, a bad one, and one that doesn't get condemned as much as it should be.
