Money can't buy happiness or friends it is true. On the other site of the story it can't take them away from you either. Everything you said here is 100% correct I just would add up that I do not put things as personal happiness and social life in correlation. There are many happy financially poor peope and vice versa. The thing is in general people who have money are on general scale happier. Here i want to say what I think why is that so. People who have money were most likely good stable people in their head with positive and opened mindset which gave them chance to get money. Because of what they are they got chance for money. Same qualities they had helped them in being happy and friendly this is the only possible correlation i see between true happiness and having money. Enjoy your day!
