Why is finding a job so hard?

I was supposed to get an engineering job (intern) but wasn't able to since I was told last minute that I needed my own vehicle, something I don't have. Afterwards, I started applying to numerous jobs and hardly got any calls. When I do get accepted in for an interview, my work experience always puts me down. I have more volunteer and academic experience than actual work experience. It's been like 5 weeks now since my search began and still no luck. I really need a job to pay for tuition and also to add value to my resume. Ever since the summer began, job hunting kept going downhill day by day for me. Do you guys have any tips on how to land a job knowing that I lack experience?
