I'm going to buy thousands of essential supplies and sell them at a higher price when the disaster happens.
That's awful. Aside from you, that's not fair to anyone else.
Not fair, but business is business.
I think that that is so wrong. You should not try to make profit when others are being faced with a disaster. It sounds very predatory.
You are being close minded. Even if the natural disaster will come and kill everyone, at least I will be rich.
Intentionally profiting off of the a disaster where many are impacted is a horrible thing to do. In addition, this is an example of price gouging and that is a crime in many places and you could quite possibly get into a lot of trouble. Please don't do this.
