@ehBeth,
Another teacher I know is my best friend who teaches 5th grade in a Chicago suburb. He makes $57,000 as a 5th year teacher and only has a bachelor degree (one that he laughs took him 8 years to get). He doesn't have any other jobs, but does make anywhere from $2,000-$4,000 coaching various programs for the school (math club, lego club, football, etc).
He's not going to be a millionaire anytime soon either. He loves expensive tennis shoes too much and probably spends $500/month on them.
He's 36 though and will be more than ok with his pension.
His father is a retired teacher who is also a millionaire. He spend 6 months a year living in Mexico.
