Go on then harris. Explain to this ignorant engineer exactly how the City creates wealth and why we don't need industry. The latter is inferred from your condescending manner of writing.
Perhaps you have read over the quite apt explantion someone else gave you the last time:viewtopic.php?f=2&t=1007501&p=84243&hilit=grubbing#p84245
You want me to explain why you don't need 'industry'? That's silly since I did not suggest that.You
don't need certain industries if your country is importing the respective products.
Germany for instance has lost most of its textile industry. It's importing instead because the international division of labor makes it cheaper. If a country manages to create its complete income from offering financial services it don't need something what you call industry at all.
The problem is that you as an 'activist' - per definitionem one may say - think that wealth literally only can be things that can be touched, eaten etc. pp. whatever (see link above).
In this view international division of labor, the structure of production relations per se can not be wealth. They may produce wealth but they aren't.( Furthermore wealth is considered to be somehow constant. Therefore the fetishist view on real estate and gold which are considered to be oh so safe investments.) Services related to trading, lending money and capital you deem to be unproductive and not wealth producing, dispensable Überbau like the marxists say, and eventually stealing and outright evil.
That's 'activist' textbook basics. Only the jews are missing in this world view - for now.
