Even if I was a wealthy person and felt bad for these people, how would I help them?
Wealthy people have much more political influence, so you would push legislation to make economy more redistributive (e.g. share remaining jobs by reducing working week to 15 hours for the same wage, implementing unconditional income, put heavier tax burden on capital while freeing labor etc).unless you want to live in the world of Elysium where 99% of the worlds population lives in a dump and 1% lives on a space-station with extravagant wealth.
If you watched the movie, you must know how Elysium ended!
