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.
Land is good investment of you want to invest for long term and you have a lot of money but many people have no big investment because they are doing job and they are running the circuit with that . They could not afford land investment as land is very costly and landlords have more interest in that but middle class people always try to buy a small house for living in which they will spend life and their family will be safe and they have not pay rent to any person. People want to invest in the thing which is cheap but best thing they should save money for the bad time which could be at any time.Thousands of people are trying to be rich and by investment in real estate industry but that industry is looking like flop industry for that couple of years.
