France and Britain was both in hard situation because of this transformation that  witnessed the emergence of new powers like the unites states of America. The second industrial revolution was the beginning of a new area of prosperity between 1880 and 1960, the automative sector is taking off especially in the USA with the methods used by the economist Taylor that promotes the work on very repetitive and identical tasks. each worker holds a position, all in line, they work for hours to ride a car. mass production has led to an increase in the demand equal to an increase in consumtion equivalent to a global increase in productivity.
