Decent jobs for someone with no degree that pay more than $20/hour?

My gf is a permanent resident and has been in the US for 6 years but has no degree, making like 18/hr with mediocre benefits. Her English is good but not perfect, and she is Brazilian so speaks Portuguese

I have a pretty good job but I'm not sure how hard it is to find a decent job for someone in her position. We are in Alpine, so something around there, Lehi, or a bit north/south would be ideal.

She feels content at her job since it is low stress, but she's living paycheck to paycheck with not enough left over for emergencies.

She's worried that if she changes jobs she might get paid more but be more unhappy, so I wanted to see if anyone had suggestions for good workplaces/jobs that paid decent
