This is a social trend wholly unanticipated by those who had expected the great advances and discoveries in science and technology to have brought about "upward mobility." This is what was looked for from the scientific and technological revolution. Instead, all of the studies disclose a clear trend in the opposite direction.
Instead of raising the level of Black, Latin, women and other oppressed workers in capitalist society to that of the higher paid, more privileged, so-called aristocratic sector of workers, the scientific-technological revolution is mercilessly and ruthlessly leveling down and demolishing the higher social stratum in the working class and reducing it to the level of the lower paid.
