Technology Not The Correct Explanation For High U.S. Unemployment
The "technological" excuse for his poor performance on jobs is quite pathetic given how other countries where technology has also advanced has not seen this drop in employment and given how in the past in the United States, technological progress has not been associated with falling employment.
Now, it clearly is true that new technology destroys some jobs. ATM's does reduce the number of bank tellers, just like industrial robots reduce the number of workers in factories.
However, as long as there are unsatisfied wants (and we are a very long way from achieving the utopia where this no longer exists), new jobs will arise. Some in creating new technology. Others in new jobs where a shortage of workers previously prevented the businesses from being created.
Thus, while in the transition process some temporary unemployment can be created by technological advances, it is not something that will in the foreseeable future create any kind of long term unemployment problem. And it is not the explanation for why the United States unlike many other nations at similar technological levels experience high unemployment.
