You think not having an active subway system is what’s keeping people from downtown LA? Everyone drives there and the parking is cheap, yet they choose not to go downtown. The same will happen to Manhattan, just like every other city with a downtown.

You see the empty store fronts, there’s space available signs everywhere right?

Edit: The downvotes don’t mean shit when Manhattan is already suffering from people working from home. It’s gotten so bad, they have to convert empty office buildings into residential housing.
