I would pay a shit ton to have loving and supporting friends, but this is not how it works. Because loving and supporting friends don't want money in exchange, but your true love and support.

This works for "good" neighborhoods if you replace "good" with "low-crime", as people with a higher income tend to do less crimes, if we count out tax evasion and other anti-society behaviours.

But this is not what it's about. You reap what you sow. You try to increase your value for people to like you and want to be friends with you? This can work, but the price for it is (1) purely extrinsical motivation which more often then not does leave you feel empty and (2) friends who will leave you as soon as your worth decreases, e.g. with age or illness, or if a different person with more value comes around and offers their friendship.
