If you have unlimited money, what's the first thing you will do?

Pay off all my family members debts. Move my close family into a decent home. A upper middle class home, I don't like gaudy mansions and super-complexes.
Start investing money into the upkeep and development of the city until there are no people suffering from poverty and hunger, once my city is done I'll move on to neighboring cities till it reaches my city's level. I'll have helpers to cover the rest of the state, continue this until the country is prospering. Continue process until poverty and world hunger is eliminated.
