Empathy for those laid off shouldn't vary based on visa status. These are real people losing their jobs, searching for another job in an already saturated market.
I've been laid off. At the time, I had plenty of savings and nobody depending on me besides my dog. I took some time off and was later able to find a new job. The company didn't have any H-1Bs at the time, but if it did they certainly would've been in a much worse situation than I was and clearly more deserving of empathy.
Did you feel any empathy when the Disney CEO was fired with a multi million dollar severance package? Things are different for different people.
