Though I am currently childless, I find the complaints of the "childless" community about favors and accomodations being tilted toward those with children rather odd. Every single person here was once a child, so every one here has benefited from the "unfair" contributions of childless people in the past. It seems rather ungrateful to me, not to pass on that gift to future generations.
I wonder, though, if there's more to the "unhappiness" of the childless. I frequently hear childless people complaining that those with kids look down on their lifestyle, though I can't say that I've ever noticed a parent make any such comment. Frankly, a lot of parents I know occasionally wish out loud that they had the freedom they used to have.
There seems to me to be an almost instinctive defensiveness among the childless. I can speak to this from personal experience, because my wife just became pregnant. When we told several of our friends (childless couples), their FIRST response was something along the lines of "Better you than me" or "Don't expect us to help with the babysitting." THEN they congratulated us. This sort of defensiveness took me aback particularly since we've never really asked or expected favors from these people in the past. Why would they assume we'd be asking now?
Could it be that those who choose to be childless these days aren't quite sure that their choice isn't selfish? I don't mean this as an insult of said choice at all.
Instead, the point I'm trying to make is that this grown-up generation is really the first where there isn't an assumption that if you're getting married, you're going to have kids. In the past, people often looked on couples without kids with pity, as if it was unfair fate that they weren't able to sire offspring. The generally accepted rule was that families would have kids. All options outside that "norm" were considered unusual.
Since, say the 60s, that norm has been breaking down, with the "traditional" family among the last to go. That leaves people who choose to be childless in the uncomfortable position of being the pioneers of a new lifestyle--this time chosen rather than being assumed to be a product of fate. It's tough to be the first people who choose something new, which means it's hardly surprising that said people might be defensive.
And, when you see a society that is still tilted toward the traditional family with children, it isn't surprising that one might rebel against that. But, at the same time, having been a product of that culture, it's equally likely that one might feel a little "guilty" about that rebellion.
After all, most kids can probably look back at the sacrifices their parents made for them and think they were a good thing. Now, though, they're choosing a lifestyle that doesn't require them to make such sacrifices. One can see the possibilities for cognitive dissonance.
Personally, I don't really care much what other people choose to do. I'm not inclined to get into a pissing contest with anyone over whether they got special treatment and I didn't. It's simply a waste of my time and I've got better things to do with it.
