To be fair, there are a lot of efficiency gains and economies of scale involved.

Google pays a lot less to provide an employee with a nutritious, healthy meal than the same employee would be paying for a less healthy meal in your typical local restaurant.

So this law will create more local jobs in the short term... except the next Techplex will not be built in MTV, which will lose it far more local jobs than it gained.

No, this is not the real point. Employment isn't an upside, that's the broken window fallacy.

Employees should be allowed to bring food from home to eat at their desks if they want, and that is obviously terrible for jobs in local cafes and restaurants.

Restaurants do have some added benefits over just a catering business though and those are mentioned in the article. Restaurants bring foot traffic to areas that other shops can benefit from where a catering business doesn't.
