Usually they "appear" wealthy because they spend their money and don't save very much. Or, have difficult circumstances happen quickly.
I would still donate if closer to them; a friend has the larger house, pool, new SUVs, etc... but it's all on credit or mortgaged or with loans. When he had a health problem, I did don'ate, knowing the backstory.
Maybe going forward he will.make different choices, but that's not my decision to make.
