I don't think happiness is measured in money. Happiness is measured in those moments that you live next to loved ones. Happiness with experience and impressions. Money is just a tool that helps to gain experience. Having money, you can arrange your life, live in comfort, travel. Routine and lack of funds, the need to save on everything, kills the happiness of being close to loved ones.
The first part of your statement is Buddhist anchored, intentional or no, nicely said. The last part though, not so much. I have been around and experienced routine (life as a whole is routine) and lack of funds for many years early in life, but it did not make me any less happy. That statement can only be apply on an individual basis depending on the persons mental state overall. If you have human necessities; food, shelter, love and family (sometimes family can suck though), then all the added things in society can be either good or bad based on attachment level you apply to them as an individual. Now if you are speaking poverty level, true poverty level, then yes, lack of funds can likely make people unhappy. But at the same time, those people are likely those that are in and around wealth and modern society structures. There are many undeveloped areas still around that have incredible people, whom are happy and joyous within their lives.
Money can give you temporary, enjoyed experiences, but never lasting happiness. As well, money can give people constant, instant gratification, which leads to unhealthy attachments. It is a delicate scale honestly and many people struggle with it through life.
Find peace inside, look for non-materialistic doings, and work to build deeper, meaningful friendships/relationships with your type of "tribe" and you will be well on the way to being happier and staying happier. Sometimes it is hard to find the right tribe in today's world though!
