Even if you have to stand now and then, you can use an ereader.
I'd pay almost as much for a guaranteed seat on BART as I would for a car.
We tolerate different pricing for various classes of seats in concerts, trains, buses, airplanes, pretty much everything imaginable. I don't see why commuter rail would be any different.
I think most people who can't afford first class on airlines do resent it, but since airlines aren't state-owned and, more importantly, it's always been there (not a new proposal), there's not much they can do.
Look at the popular outrage about scalping. People absolutely feel that you shouldn't be able to buy your way into a good seat, and instead ought to be lucky/first.
It's hard to take what you're saying seriously when you're so clearly biased towards one end of the political spectrum.
The actual truth is much less political. Cities like New York City are way too dense for everyone to drive a personal vehicle, full stop, your non sequitur about Audis notwithstanding. Mass transit is the only transportation method that scales to handle a population the size of a large, dense city. Individual vehicle transportation does not. It doesn't matter if you're rich or poor, whether you're driving an Audi or a beater; if you're trying to drive to your job in the heart of Manhattan from the suburbs it's going to take you hours. Mass transit is the better choice for almost everyone.
In a car, I have to be on moderately high alert the entire time I'm driving, especially in traffic.
Edit: And it's the exact same for the Long Island Railroad, which is the other major commuter rail system run by the MTA. They have a third system, the Staten Island Railway, but I've never taken it and thus can't comment.
It may actually be a good strategy to live even further from the city if it lets you switch from a crowded urban transit system to a more spacious suburban one.
It's a good question though (let's put aside costs for now): How much more time would you be willing to spend on commuter rail over heavy rail if it means getting a seat? I'm not sure. I think I'd rather be seated for 40 minutes than standing for thirty, but at an hour, I might just prefer the shorter trip. You can still easily listen to podcasts on crowded heavy rail, or get good at holding a Kindle in one hand.
Also, you don't see that here in NYC. People are gonna sit down if there's space available. Unless it's next to a crazy homeless person, but I've only ever experienced that on heavy rail, not commuter rail.
In smaller cities, it takes less time to get downtown from the suburbs than it does to get across downtown on foot or even a bike. (Buses there move at walking speed in the average case, or bicycle speed in the best case, but only come every half hour or so).
I have some friends that have moved to upstate New York from Brooklyn and rent is the same, just with a lot more space. However, you then have to add on $400/month for the commuter rail along with an extra hour per day of commuting, plus owning a car and needing to drive everywhere instead of walking. It actually ends up being more expensive, but the trade off is getting more space (if you care about that for some reason).
Or to "the rent is the same, but I don't have to have roommates" by not having them.
