I believe that money is the root of all evil.. I think if we just care about humanity, not luxury and money, there will be a better world. Change should start on ourselves. Honestly, if you want change the world, you should start from yourself . You should have a discipline. Think about what can you give to our society to make it better. Build a business, give opportunity to the jobless people, hire them. Something like that. That makes your life purposeful. 
Everyone has their own thinking but to me i do not think so. to me i think that money is the solution of every problems and can protect you from such evils. you just need to use your money in a good way and for good purposes, so it can only depend on you that how are you going to use your money.
