There are plenty of high school and college graduates that can do elementary school math. They are just going into more lucrative fields. If Ford wants those candidates, they need to offer more competitive salaries.
You're likely being underpaid. I'm in Iowa and regularly see software devs with offers higher than that. The last company I was at, they brought an intern back with a $140k starting salary. He was making more than an "architect" who had been at the company for 16 years.
I'm not in SV either and $120k would be well below average for someone with 30 years experience in my area. Of course, "in tech" can mean a lot of things. From what I have seen, tech writers and IT help desk folk don't make nearly as much as SW developers.
That sucks, i learned JavaScript during the pandemic and make more than 120k at a corporate gig in Chicago (where salaries are certainly higher than Wichita but it's no SV). I don't even have a college degree.
