Well, you can enjoy today, but have you ever considered about future? What happens if there is influx of migration from Delhi? Are you going to enjoy that time too?
I think as a human being we should try to empathize other's problem. Imagine if elites openly says "I am enjoying lavish life using the money \"stolen\" from the poors".
The original comment was similar to "Meanwhile I am enjoying in Bangalore". It may be jokes, but making jokes on somebody's dire situation isn't helpful to anyone.
