Stock market. The law of conservation should work for money. By creating money out of thin air, we condemn ourselves to crises leading not only to wars, but also to belief in luck — a false source of life and enrichment, thereby diverting a significant part of the population to worship it instead of trying to become a scientist or just doing something useful. How long will fortune allow us to survive?
If the shares are to be used as a tool for investment-raising funds, there should not be an opportunity to quickly buy-drop them for the purpose of instant enrichment. Shares must remain with the new owner for at least a year after purchase.
Games. Gambling and non-gambling. Casino and MMORG. All this staff should be branded as interfering with our survival.
