I think that things like spending 2500 a night for a hotel when you can be quite comfortable in an 80 a night room are the things I'd think are extravagant. Maybe the extra 2420 couldn't help a lot of people, but it could help a couple.
Old story:
One morning an elderly man was walking on a nearly deserted beach. He came upon a boy surrounded by thousands and thousands of starfish. As eagerly as he could, the youngster was picking them up and throwing them back into the ocean.
Puzzled, the older man looked at the young boy and asked, "Little boy, what are you doing?"
The youth responded without looking up, "I'm trying to save these starfish, sir."
The old man chuckled aloud, and queried, "Son, there are thousands of starfish and only one of you. What difference can you make?"
Holding a starfish in his hand, the boy turned to the man and, gently tossing the starfish into the water, said, "It will make a difference to that one!"
Everyone can help someone on a small scale. No one can help everyone.
I don't think we are required to sleep on the floor or eat beans all the time, but we don't have to have the BEST of everything with no thought of helping others. Most of us can't do anything GLOBALLY, but LOCALLY -- we may be able to make a difference in small and large ways.
