Where are you getting the information that New York's problem isn't as bad?

He must have visited the city and walked around. The population might be larger, but the problem is less egregious in NYC; we don't just let them camp out in the streets and rule the city.
NYC has a homeless population of 76,501, but according to HUD, only 5.1% of NYC homeless are unsheltered. In SF, the unsheltered rate according to HUD is almost 90% - nearly the worst in the country. That means NYC actually has fewer unsheltered people than SF on the streets despite a much larger homeless population.
So while NYC has a big issue with housing affordability and homelessness, they are actually doing a much more effective job of keeping people off the streets and reducing the rate of the kinds of severe public health issues you will see everyday in downtown SF.
The most current stats I have indicate that California has about 25 percent of the nation's homeless:

NYC now shelters most of its homeless mainly because state law requires it. We’re spending a ridiculous amount of money putting homeless people up in hotel rooms because the process to get new shelters built is stalled and we can’t even build enough market-rate housing to account for population growth, let alone affordable housing.
