Who gets it?

Hence it has happened that the development of steam navigation, of railroads and telegraphs, of mechanical and chemical science, and the growth of the population, while enormously increasing productive power and the amount of material products—that is, of real wealth—at least ten times faster than the growth of the population, has given that enormous increase almost wholly to one class, comprising the landlords and capitalists, leaving the actual producers of it—the industrial workers and inventors—little, if any, better off than before.—Professor Alfred Russel Wallace.
