The marginal voter doesn't have grievances like that unless the country is seriously in trouble (like it was in 2008 and 2020.) They're not paying close enough attention to have them, nor do they have clear ideas about which piece of government is capable of addressing which problems. They have better things to do.
If you talk to the median voter their thinking will be like "something happened three years ago I was mad about" or "my husband wants us to vote this way because he saw it on TV" or "the Democrats want to legalize incest" or "I like voting for whoever I think is going to win" (and yes these are all real.) They especially do not have coherent opinions on economic policy.
Mainly the problem is the US doesn't have a coherent media ecosystem anymore and Republicans were better aligned with newer media, ie Facebook posts and bro-y podcasts like Rogan. So TV ads and "ground game" don't work.
