I have to read your composition severally to enable me to understand exactly what you are emphasising on, but i could not figure out the
scenario or exact point. But it seems that you are making emphasises on economic hoarding that will uplift the country. From my opinion i want to let you know that people that is holding almost 80% of economy of a country and from your assumptions you think it will lead the country to economic setback.
Human don't hold economic function of a country except government so i think what causes economic setback of a country is because of government strategies, plans towards the nation, actually a poor country find it very rigid to get out from economic recession and it's base on plans that will restructure the country.
Imagine this, the regular people live with 300$ a month, but the average looks like $2.5k a month because one guy is so rich that he increases the average. So one guy having 5+ billion, while others have 300, and that makes the average $2.5k instead. That means from the outside and from the economical statistics the nation looks "fine" but in reality the citizens are living a rough life. I know this because I live in an a nation with almost like this.
Of course it is not just one person here, we have 45-50 million living under $400 a month, and around 20-25 million living under $1k as well, it is just a few million people living above $1k and yet we have a $6k monthly average on statistics. That is quite similar to what I talked about, only difference is it is not one person in our country and like a million people.
