Do teachers actually make this little or is my brother exaggerating

I have 4 kids, my older sister has 2. My younger sister is in prison so my mom and dad have her 4 kids. Basically we all have kids a responsibilities. My brother is the only one who doesn't have kids. He just has a dog. He never tries to help the family. He inherited a house from our grandmother so he doesn't have to worry about rent. He won't help any of us. Even our parents that are raising our nieces and nephew. My brother's excuse is he's a teacher. He doesn't make much. He refuses to put family first when we are all struggling with kids. He claims he makes $2,000 a month after taxes. He works as a special ed teacher at a private special needs school. I know teachers don't make much but that honestly doesn't sound right. 24k a year? For a job that requires a bachelor's degree? Any teachers that can give me insight? Because it sounds like he making it up so he doesn't have to help family.
