I'm afraid most of the millennials will be wiped out by this economically.
Most of them already had a slow start, as the economy crashed right after they were done with college/university.
They got their jobs late, they lived with their parents longer and most of them finally got something going between the age of 25 - 30 and were looking to work out a retirement plan, settle down, buy a house or plan for kids.
What little they had managed to save will now be spend on daily necessities.
Unless a miracle happens, Corona-chan wiped out an entire generation.
