No, not all things can buy by money like happiness or your family's love for you or your friends or family's trust.
In today's world, we cannot survive in this world without money. Everyone is in great need of this but everything has its own place and we should not replace it with other things. Money is important but that does not mean only it is important. We cannot survive without knowledge and relations. Good behavior cannot be replaced by money. We cannot earn respect with money.
