It has just occured to me, just like Eureka! Optimisation may be the concept that could lead to economic Recovery, not only in Europe, but everywhere!
The European Central Bank could encourage industrialists as well as managers of SMEs to borrow some of the huge mounds of cash they have. Some days, I read that 720 Billion Euros are being parked with the ECB overnight, but hardly few hundred millions are being borrowed on any given day. Europen commerce and industry must develop a bigger appetite to borrow and invest and create wealth....work creates profit and wealth. That will be the way forward.
As for Greece, if the population there collectively decide on whether they wish to stay in the Eurozone or pull out, then they can determinedly move forward in some one direction, without causing jitters around Europe and the world. There is the great idea of using the sun and wind that Greece is blessed with to generate solar power and wind power, and sell that onto the rest of Europe. Huge investments would be needed; where would that come from?
Once there is direction, and investment to bring it into reality, work will be created for many people.
Just think, when there are empty houses and commercial buildings, and there are people looking for work, and banks who don't seem to find borrowers, the solution may be for government involvement - like a Father may guide his children. An economy that works like that, would do well.
The concept of Optimisation in the economy is this: Instead of giving social security, give people work, so that it saves on giving social security benefits and housing benefits and instead giving people a pay-cheque so that they can buy houses, pay taxes and so on and on. The empty houses would become filled, as would the empty shops and offices and industrial warehouses, and the economy would once again begin to thrive. The fiscal deficit would be cut, with revenues on the positive side. The national books would get balanced. And an unnecessary recession (soon after the longest recession in recent history) would be averted, bringing joy to all citizens. Heatmaps of happiness, like heatmaps of green.
