1. worry is drastically reduced.
Of course some people find other things to worry about like their weight, their healthy, their children etc, etc. but where the next meal is coming from and how to afford new shoes is no longer an issue.
2. ability for enjoyment is increased.
That's not to say that anyone with money will use that advantage. But the ability is there. People find enjoyment in lots of different ways, and yet almost everything has at least a small price tag attached. Even a family picnic involves paying for petrol and food. And some people find enjoyment by helping others (I know I do). With money on hand that is easier. Just look at Oprah Winfrey. She gets an enormous amount of joy out of helping others and she herself said that she has the ABILITY to make things happen because of her wealth.
Yes, yes, it is possible to exist in life with less money. And there are millions of people out there living in very basic conditions. Some may even choose a more simple life to reduce worry and increase enjoyment.
But it doesn't change the fact that more money usually opens doors.
I consider myself extremely fortunate that I live in a country where comfortable living is considered the norm. I don't NEED anything else. If I can remember that next time I want something, I'm fairly certain I'll live a happy life.
