It will have the effect of narrowing portals of entry to the workforce. Fast food restaurants may have 100% or more annual employee turnover rate. Most leave when they find better jobs. According to company estimates, one in every eight American workers has been employed by McDonald's at some time. If half the jobs in a fast food restaurant are replaced by automation, that's half as many who will gain entrance to the work force. (It does create a permanent underclass of Democrat voters who are dependent on the government for their every need.)
The automation created to replace low skill workers in turn creates a higher paying, higher skilled job for someone to maintain and repair the automation equipment. That job will not go to a minimum wage flunkey.
