Dave Ramsey, quoted here:
If I raise my rent to be market rent, that does not make me a bad Christian. I did not displace that person out of that house if they can no longer afford it. The marketplace did. The economy did. The ratio of the income that they earn to their housing expense displaced them. I didn’t cause any of that. And so you are not displacing them. You are taking too much credit for what is going on …
"Not my problem" is man's perennial problem:
But you say it is all right for people to say to their parents, 'Sorry, I can't help you. For I have vowed to give to God what I would have given to you.' In this way, you let them disregard their needy parents. And so you cancel the word of God in order to hand down your own tradition.
-- Mark 7:11ff.
