Corruption/money laundering

Recently,I have watched a film which was related to corruption from huge companies which have effect on authorities and even government.However,I have thought that whether problems about money laundering is positive or negative impact on citizens'life.Clearly,corruption occur in developed countries,inhabitants in these countries live,work as well as have all of living conditions better than dwellers in developing countries and It's highly likely that corruption still take place in developing countries.Numerous people said that problems related to money laundering which happen in many countries cause country where go down,it's undeniable that individuals'life on all over the world are more and more thriving and morden.This difficulty is my question

Please discuss with me about this problem.thank you
