1) You're guessing about what's going to happen in the future like it's a complete given that only good things would result from this and enough other states would join in. I would point out that (this doesn't involve speculation) we already know that some companies don't want to compete in locations that have these policies, which isn't ideal for New Yorkers.

2) Your positive speculation might be a little more reasonable were we entering great economic times where companies were rushing to hire anywhere they can. In troubled economic times, companies have a lot more leverage to seek the best deals they can and can exclude locations that are more trouble than they're worth.
