Money can't buy happiness, so there must be other reasons why so many Americans aren't happy.
I'm going to throw out a crazy thought and say that American unhappiness could be a result of 1) highly polarized political climate that encourages and incentivizes hating your neighbor and breaking off friendships and disowning your family if they vote for "the other guy" and 2) a weirdly persistent narrative that everyone should be happy all the time and that if you're not always in a state of unending bliss there's something wrong with you that needs to be medicated and that any emotional dissatisfaction or struggle is massive trauma that can't possibly be overcome without everyone in your life accommodating your every whim.
I doubt that, since the US has been rated unhappy for some time and it's only recently that some people have cut out friends due to politics. I have plenty of friendly acquaintances and one close neighbor who voted for Trump. My family all voted for Dems, but I have friends who have family members who voted for the Rs and they are still very close, so I do wonder if that many people have really cut others out of their lives over politics. I'm skeptical.
Btw, I don't think Trump supporters are terrible people at all. I personally know some dear ones. I just think they've been manipulated by a cult leader or they don't understand the man's history, get their fake news from places like Newsmax or are simply low info voters. On the other hand, my wealthy brother in law voted for him for the tax breaks, but after talking-to him a few weeks ago, it was obvious that despite being highly educated, he was a rather low info voter too.
I doubt the happiness thing means one needs to be ecstatic all of the time. It probably means that you are basically content with your life. But clinical depression does usually benefit from some type of treatment. it's a medical condition, but that has nothing to do with Americans not being as happy as people in other countries. I am content, but of course I've gone through very difficult times, but so far have been able to move on. I have friends who are miserable due to clinical depression, financial struggles, the loss of a spouse or just plain loneliness.
My other post wasn't to be taking too seriously, although giving does usually bring one joy. The friend who I've given the most to, would probably give away something that someone else needed more than her. She never complains despite having plenty of difficulty in her life. She's poor, and has some serious health problems, but she has a loving family to help her cope. It makes me happy to give to her.
It just seems to me that Americans would be happier if they were more generous, even if it's just be doing volunteer work. I've done it before and it can be very emotionally rewarding. I'm not saying that's the only thing, but it certainly would help.
Did you know that homelessness increased by 18% this year according to an article I read this morning? I guess if we took better care of our poor, there might be less sadness too.
