This is terrible for sure, but it's worth remembering that 60% of all restaurants close within their first year of operation and 80% within 5 years. The restaurant industry in a city like New York is incredibly cut-throat.
60% of all new restaurants close on the first year. That is very different than half of *all restaurants, even those that have been open for decades, closing in a single year.
I think the more important distinction is that this is 60% of ALL restaurants, not 60% of the 10% of new restaurants (or 6% of restaurants).
(I made up the 10%, but I'm sure it is small.)
