According to the economist, one of the problems that Europe and the United States will face will be the increasing age of the population. This will affect Europe more because the average American has a shorter life expectancy.
Paul Krugman explained that this is due to so-called deaths from despair, that is, premature deaths related to drugs or suicide.
"Europe, depending on the country, has a real problem. Too few workers pay into the pension system and too many retirees use it," he said.
One way to deal with an aging population can be through migration. Paul Krugman assured that he views it positively.
"My grandparents came to America because of migration," he said, but noted that "it's important where your migrants come from and what their culture is."
"The experience of the United States of America in terms of migration, although people do not believe in it, has been really positive," said the winner of the Nobel Prize in Economics, adding that the crime rate among immigrants in the United States is "quite low."
In his view, places like New York, which receive large numbers of migrants, are "doing well economically and in terms of public safety," although Paul Krugman noted that it is more difficult in Europe.
