Money doesn't buy good memories, but it sure helps finance many opportunities to make them. It's neither necessary nor sufficient, but that doesn't make it highly enabling.

You need to consider the opportunity cost too. While you were camping in the bush, you weren't earning.

I don't know why you were downvoted, your statement is right. For example, if someone have financial problems for some reason and have to work 2 jobs to deal with it, he/she hardly could get out camping with friends. Money can buy you spare time which you can fill with uncostly memories.

Yea, it's good relationships with people. I'll throw pets in there too. Some of my best friends have been dogs, and cats.(Some might consider this pathetic, but my pets were important part of my life, and I miss them all. Hell--I don't consider them as pets--they were family members.)
