Well. If you have depression and you’re a business owner or small trader for example. It would be impossible to get out of bed some days and feed yourself. So id say it’s one of the most important financial fixes for every human.
You took it as if it needs to be a fix just so people can be happy. Happiness doesn’t mean you’re surviving.
Yeah I agree, depression is a bigger deal than those things. But there's also heart disease, obesity, etc that are along the same tier of health issues with massive impact. But the #1 biggest issue imo is the length of commutes. We would all be so much more productive if we would all move to perma-WFH.
If we could get rid of depression a lot of other things you mentioned would go away too. A lot of unhealthy lifestyle comes from lack of clear thinking and escapism.
