Anyone who can get in a car is 'privileged'. Anyone who can buy an airline ticket is privileged.
I find the whole, "Oh, I can't afford to fly if I have to buy my baby a ticket" is completely disingenous. If it was the law (as it will be within a few years, a lot of us are working very hard to get rid of the lap-baby loophole and the FAA is completely onboard), you'd find a way to pay for it if you're flying in the first place, as you will the moment your baby turns two.
The number of people who stop flying when their child turns two, but flew anywhere and everywhere up to 23 months is pretty much non-existent. My guess is, if you were legally required to, you would.
You are, of course, completely welcome (for the time being, until the law changes) welcome to disregard my advice, but making personal attacks simply makes you look foolish.
And if you can scrape up for X months to buy 1 or 2 tickets, you can scrape up for X number of more tickets to buy the third.
