Mega-Millions is now a Billion!

I find it strange that people will line up around the corner and buy tickets when the first prize is a billion dollars, but don't bother when the prize is a paltry 30 million.
It's like it's not worth their effort and investment to win 30 million, but it's well worth it to win a billion.
Statistically, you have a better chance to win the lower prize as well.
Psychiatrists must have a field day with that kind of logic!
I'm one of those that do that. To me it's because the odds of winning are so small, it isn't worth it. If I'm gonna fantasize, lets make it a HHUUGGEE fantasy. LOL
