This is a great topic, and indeed, in this life, we do need to implement such a system. If we could implement a system like the one you mentioned, it would certainly have the potential to improve our economy, making it progress over time. As you mentioned, healthcare costs are already funded, and everything is allocated accordingly. So, of course, we wouldn't have to worry about the hassles of life if the system you've created were implemented.

I often hear of people experiencing sadness and so on, and this is indeed caused by a lack of financial management and not following rules when receiving a salary, etc.

However, I will add a little, of course, regarding investment. One thing you haven't mentioned is land investment. I believe land investment is equally important, but of course, if we can afford it and our salary is sufficient. I'm sure this topic is very useful, Op.
