you do realise builders carpeters etc make boat loads in the U.S., too? maybe look at the New York construction salaries (who is part of the Union)
regardless, i think you are believing a narrative that the left media want you to believe. there are more colleges educated people voting for Harris. This is true. The states that are hard blue are 'generally' states that having a degree is essential for employment outcomes
whilst a lot of southern states have farming mining, oil drilling etc usually requiring technical skills to earn a higher income.
being 'educated' means looking at the data and understanding it, not just scream figures like you have done above which shows me your are either poorly educated or just lacl basic data analysis.
regardless, there are ultimately only 7 states that will determine the next election with the voting being that close no matter who wins America will be incredibly divided
im hoping Trump gets it done simply because the Dems will likely bring us to world war 3 which might happen no matter what but at least with Trump and the Reps they might stop the blood shed thay Harris/Bidan has allowed to happen
for example Victoria is the most edicated state in Australia but it is by far one of the poorest compared to W.A which has low edicated numbers but very high wages
