An over-valued financial asset is thin air and creates nothing only the illusion of money. Add to that the ability of our current banking system to give Y-times more debit then their deposit (where Y -> OO+ ) one the one hand, on the other hand there are people producing items of value that we can actually use.
The rate at which over-valued asset are sold and re-priced + banks giving away loans that they will never get back and didn't had the money to support them anyway is orders of MAGNUTUDE bigger than the primary sector and secondary sector can produce.
There's also the problem of automation of the mainly the primary sector which makes things even worst. Now we have to create virtual scarcity in order to maintain this totally insane system because, let's face ... With today's technology 1 country could produce enough wheat for 5 planets.
More efficient options may exist but to the best of my knowledge none currently do
People working, manufacturing and creating things are what creates wealth. Not a magic money tree.
