The alternative to good public transit for everyone is bad public transit for the majority and cars for a few.

You don't get to imagine an alternative like "cars for everyone", because it's simply not possible.

That is literally what we have now.

I don't recall receiving my tax-funded F-150 from the government this year.

No, in most cities most people by far use public transit for their commute. And in most cities, especially where this is not exactly true, car traffic is already hellish at rush hour.

I wonder what most of the commuters do at work? Sit in front of a computer maybe?

What does that have to do with anything?

I do agree that work-from-home should be a part of the transit solution. But not even the entire software industry can work from home, nevermind all the other industries that sometimes use computers.
