Essentially, he stands for a neutral strategy of the linkage between technology and American points concerning unemployment and declining wages. The notion of acceptable technology was developed within the 20th century by thinkers similar to E.F. Schumacher and Jacques Ellul to explain conditions where it was not desirable to make use of very new applied sciences or people who required entry to some centralized infrastructure or parts or skills imported from elsewhere. A more infamous anti-technological treatise is Industrial Society and Its Future, written by the Unabomber Ted Kaczynski and printed in a quantity of main newspapers as a part of an effort to end his bombing campaign of the techno-industrial infrastructure. There are also subcultures that disapprove of some or most technology, such as self-identified off-gridders. On the considerably skeptical side are sure philosophers like Herbert Marcuse and John Zerzan, who imagine that technological societies are inherently flawed.
