A modest amount of protectionism is alright. There are enough services needed to provide jobs. Tariffs can be created with the environment in mind. But if you want to prevent consumer products from low wage countries where there is no pollution regulation what so ever and employee abuse , you must first look at what is happening in your own country. If you set tariffs this way, automatically the products will rise in price and local manufacturing will be more desirable. In the end, quality will mean more then quantity and then you are automatically entering the rhineland model. Your workers feel an obligation towards the company as if it was their own company. And when the country is seen as part of the company, pollution is also automatically not desirable. What politics and economy misses in the world, is the scientific method. There is no feedback to perform corrective measures. There is none to hold responsible. A CEO and his or hers managers can bankrupt a company but cannot be held responsible. A politician can endanger lives of people but cannot be held responsible. For me personally it is fine if a CEO or a president earn tens to hundreds of million of dollars or euro's a year. But the other side of the coin should then be that they can be held responsible in the case of of negligence. If someone creates long term stability then it is fine with me if that ceo receives a billion dollars or euro's over the course of a decade. But only if it means that a lot of people will have a living and an earning for that same decade and decades to come.
Intermezzo :
An electronic circuit called integrator is able when placed in a feedback loop to perform corrective measures when the measured output is not equal to the desired output.
One could argue that a manager in a company is such a feedback instrument. But that is not always the case because more then often, a career manager only looks at his or hers own career. A company does not benefit from people who only plan to enrich themselves at the costs of others. Interim ceo's and manager that are pulled in externally from other companies do not want the best result for the company. They want the best for themselves. By nature they will reduce efficiency because of the greed they have. A real manager is as much interested in the work that the employees perform as the employees themselves. Only then optimizations can be made.
The basic flaw in politics and economics is that there is no true corrective measure, no true feedback. The most basic electronic circuits are circuits that perform a feedback function to minimize any errors that may occur. But these circuits need a reference and what is the reference needed for politics and economic policies ?
End intermezzo.
When economic policies are created, then automatically the policy makers must ensure that the economy works as a giant flywheel. Stability and minor upsets do not cause massive failures. Integration and differentiation. I cannot find it in politics and economics. But it must become part of it. theoretical math models are of no use. The scientific method is all that counts.
