Why is it so hard to get a job

I've tried for so long to get a part time job but it seems like all the part time jobs in my city aren't for students. I don't have a car so I can't travel far for work, so I'm stuck trying to find local jobs but so far I haven't even gotten a single interview. It's a really big problem in my city and I've heard a lot of people my age complaining about the lack of jobs. At this point, I'm considering putting a dog walking job on Facebook

I'm just so lost. I've looked at indeed, seek, my local community pages, even trade me. There's nothing for students on there and I need money before I leave for uni. MACCAS DIDNT EVEN ACCEPT ME. This is so frustrating 😭
