A lot depends on your local educational system. Community colleges in California, for example, have suffered large budget cuts and many teachers have been laid off over the past few years so it's not a very attractive career. A program with few offerings is not attractive to students, either, so budget cuts tend to lead to enrollment drops:

A main issue, at least in the USA, is that college is extremely expensive so smart students who don't want massive debt or who can't tap parental wealth can do two years of work at a community college (with smaller classes) before transferring to a four-year school, saving tens of thousands of dollars along the way. Some community colleges have reoriented around this goal to attract students, but the tradeoff is that continuing education for adults and other vocational programs often get cut.
Another problem is that public high schools do such an atrocious job at instruction that community colleges have to pick up the slack, so you have schools teaching basic algebra and simple reading/writing skills (i.e. 9th grade level etc.) to young adults whose primary education was a disaster. It's a pretty sad state of affairs, at least in the USA.
Note that teaching at a CC tends to require at least a Master's degreee in the field, and of course if you have large student loans the pay is to low to make any headway in paying them down. Incidentally, if you are planning to teach, LLMs have huge potential for new teachers to design a course with modern material. Of course grading students is going to be an issue and in-class testing is the only plausible alternative as LLMs can also write code and solve problems for students.
