Boyfriend’s career choice

My boyfriend wants to be a firefighter but I’m worried that’s not a good career choice. From my research, it seems like they don’t make a good income. Like $45,000 annually. My job will bring in $85,000 annually (these are approximately). I’m fine with being the one who makes more money but is this enough to support a family and live nice? I want to support his dreams, but I don’t want to risk financial issues because of it. Any firefighter wives out there? Or anyone who can offer advice or an alternative career choice for him? Thanks in advance
