> How many elections have you voted in or been eligible to vote in where a single vote being added or removed would have changed the outcome? Zero? Cool, me too.

So if you aren't the one, single deciding vote it's not worthwhile? That's an immature approach. All the more immature because you go on to couch it in rhetoric about economics and "rationality" that amounts to nothing more than third rate sophistry.

You're not a taxi cab that has to be in service 24 hours a day to maximize utilization. You're a person with responsibilities. Your "economic rationality" is just a lazy justification for only doing what you feel like doing ("provides marginal value!") and never doing anything you don't.

If you're going to be a bum, be honest with yourself and those around you.
