No, its the other way around.
Myspace is infested with two things.... 13 year old girls and 40 year old men trying to pick them up. Throw in a bunch of porn stars, a few musicians and a handful of us (the general public) and you have myspace.
Facebook was initially geared toward college students, but has since expanded to high school as well.
What makes facebook so "safe" is that,unlike myspace, regardless of your profile settings, you need to either directly message somebody or add them as a friend for them to view any pictures other than your default picture, your school, and hometown. Like myspace, you can limit who can see your profile. But unlike myspace, facebook gives you the option to control who has access to what. For example, I can set my profile so that all users in my Rutgers network can see the pictures I put up, however only select people can see the ones I get tagged in etc etc. Also, only my closest friends can see my videos. All of my "friends" can see my email. One of my photo albums is only visible to my family members and closest of friends. My "wall" is visible to all of my friends with a few exceptions. There is just a lot more flexibility as far as controlling who can see what, and being safe, without sacrificing things.
But ultimately, it all comes down to your common sense (lets not post addresses, home phones, specifics of employment blah blah) and how much time and effort you want to put fourth in setting up your privacy settings, because your profiles are very open as a default.
Facebook is a nicer set up that allows people to stay in contact and keep up with each others lives easily, without provisions for people to put up obnoxious flashy back grounds and stupid things like that.
