They sure do. You guys are spot on. Here's what I think.

Reasons:

1. Stupidity and faith in their government

2. Being a part of something bigger. They'll never be famous but here's a chance to latch on with all of the talking heads in media, sports and entertainment. They're part of the in-crowd they believe.

3. Power & control. Some people love it. Even if it means killing your neighbor. See: every dictatorship ever.

4. Lack of faith in God. These people seem to not have come to terms with, when God wants you, he'll take you. Whether you're 5 or 85. They think they'll live forever.
