At least in my game, people always make the time and effort. Sometimes though, things come up. Someone's mother dies, kid's need to go to the doctor, they have to work overtime, etc. What effort should they have put in, that is clearly not good enough for so many of you? Why do you feel the need to judge people's lives in a way that you feel the need to not "reward" them?
It's a game.
In the situation of sickness, a death in the family, medical attention for the kids, etc. then things can be overlooked. As I mentioned, in our group all you have to do is provide your character information. They can email it to the DM or post it on a messageboard that I created for the group. It's that simple. Then when they can't make it, we have access to print the information out and play the character (which I usually do).
The "It's a game" attitude doesn't fly for me. Yes, it's a game, but at the same time you have a committment to the group. I'm not saying the group comes before your family, but it is the lack of committment and common decency that irritates me.
When a player misses a session, especially in smaller groups, that makes the group suffer. At one point our group only had 5 players. My DM has a strict rule that if there are less then 4 players, the game would be cancelled. Everyone knows this in the group. If one person misses, I usually take up the reigns of his character along with my wizard (and running two wizards or a wizard and a psionicist is not fun, let me tell you). However, we had a couple sessions where 2 people missed and one of them didn't notify the DM

So, the rest of the group drove over an hour and we didn't end up playing.
Now, some may say that is the fault of the DM, but since it was a rule that everyone knew, it was the fault of the players being inconsiderate and rude. All they had to do was pick up a phone and call. I get together with the group to play DND, not board games or to sit around and BS. I can do that with my wife at home or with our other friends, and not have spent the gas money and time to drive there and back.
Edit -> There are times when a player is
too dedicated

We had one player that actually showed up to the game to give us his character information while his wife was in the hospital in labor

We constantly tease him about it now, even though he tried to explain that the doctors said she would be in labor for at least a couple hours. By the time he got there, they had already called the DM to tell him to turn around and come back (since he didn't have a cell phone on him).
