Rensi, who was McDonald's CEO from 1991 to 1997, isn't the only fast food executive to be concerned about the consequences of raising wages. Wendy's is currently testing self-service kiosks in a few of its restaurants and exploring broader uses of technology to mitigate rising labor costs.
Instead of a federal minimum wage, Rensi says states should set the figure based on cost of living in their region. He warned that a higher minimum wage would damage the economy and leave more citizens dependent on government support.
"We've got unemployment in the black community which is staggering. Young black men over 50 per cent unemployment, and we're talking about a $15 minimum wage?" said Rensi, who most recently served as CEO of the restaurant company Famous Dave's. "It's nonsense, these are entry-level jobs."
Last year, Rensi told The Washington Post that when he started working at McDonald's in 1966 there were 70 or 80 people working in the store, a number that has been cut in half today.
As computers have grown exponentially more powerful, companies have been able to automate more tasks, diminishing the need for human employees. Robotics and artificial intelligence are hot areas in the technology sector, and the World Economic Forum estimated earlier this year that their rise would cause a net loss of 5.1 million jobs over the next five years.
Some experts are so concerned about looming unemployment that they are calling for a basic income, a regular stipend to be paid to citizens who are likely to lose their jobs and cannot be retrained. Several European countries are planning experiments to test the impact of a basic income.
