One group produces virtually no waste in society, while the other is notorious for it. They do have something in common though. Namely that they don't have any or they have very little money problems. The billionaires, for obvious reasons, have financial security, but so do the Amish. The Amish for another reason though, namely that their thrift and financial conservativeness is legendary. The phrase "Amish millionaire" isn't an oxymoron, it's become more of a cliche.
The Amish are notorious for their spartan lifestyle because it part of their customs that they cannot rely on the outside society, hence no public electricity, city water, or gas powered machines. They have to be self-sufficient. While billionaires are exposed to the roller coaster ride of society, they are also for the most part isolated. Not because they choose, but because they are capable.
During the great recession of 5 years ago, these were the only 2 groups that really weren't impacted like the rest of you. As a matter of fact they thrived! The Amish bought up lots of foreclosed land and the billionaires (if they weren't too leveraged) bought up massive amounts of under valued assets. The rich got richer, the poor got poorer.
Now you have a much greater chance of becoming Amish than a billionaire, but there is something to be learned from both, namely retirement. See the retired are very happy also. Not as happy as these 2 groups, but still pretty close and it's for the same reason. They have sweet sweet freedom.
So if you want to be happier, adopt the Amish lifestyle of use it up, wear it out, make it do or do without. You'll see your wealth grow to the point of at least feeling like a billionaire, if not actually being one. Financial security in the end is what it's all about.
