In the past two hundred years, technology has transformed the human workers environment more than in the thousand years before. Until 1840, more than 70 percent of the American work force were employed in agriculture, now it is less than 2 percent.
The freed labor found employment first in the manufacturing sector and then in services. Now, with robotization, the speed of substituting labor through machines will accelerate and artificial intelligence will increasingly substitute labor in the service sector.
While technological progress destroys occupations, innovations make the economy more productive. Wealth, rightly understood, is productivity. A rising productivity means that less labor is needed to produce the same amount of goods. The higher the productivity rises, the richer we get.
The problem that we face is not the threat of unemployment. The real problem is that social resistance against the loss of certain jobs may emerge and an anti-capitalist mindset may prevail and hamper economic progress.
But in a free society, human workers, robotization is not a threat but a boon. A better future does not only require the continuation of robotization, there must also be a parallel move to free capitalism.
In a world with highly automated production, and without a state in the conventional sense, the cost of living would be only a fraction of that of today and obligatory contributions would take only a negligible part of income.
