So are you asking if everything is easier with money or if you have less stress when you are rich than when you are poor?
I think a lot of the most important issues in life aren't related to money - having a good marriage, having true friends, teaching values to your children, etc may actually be more difficult when you are wealthy because the money can make things more complicated.
I have, like many other people, dreamed of winning the lottery. And I have also thought about the changes in my life that would occur along with that. Would my child have no respect for the value of money? Would he get an attitude that he is better than others who don't? Would I get lazy because I had too much free time? Would I know if people who wanted to be my friends just wanted my money? Would I lose some trust and faith in people because of that? Would DH and I fight over how to spend/save the money? Etc. Once I really thought about it, I realized I probably would be just as happy where I am now, where something unexpected like needing new tires can blow my carefully figured out budget for the month. To me, the things I value most in life don't have a monetary value. However, I do agree I would have less stress when it came to finances.
