First, it's based on the same older self-reported exit polling that led 538 to completely mispredict the election, so you should immediately be skeptical of the data.
Second, it only takes into account self-reported current income blocks, not change in income over the last decade or so, which is what many Trump voters are angry about. For example, making $70k today might seem ok if you look at the table and see median state income is only $65k, but that means nothing to someone who made $90k in 2007 and has never been able to get income back to that level.
Third, it also ignores future predictions based on current state of affairs for voters. It's not very comforting if you make higher than the median income in your area, but your job is on the chopping block. Trump picked up far more non-college educated voters, for whom future job prospects look worse and worse every year, even if they have gainful employment today.
Unfortunately I do not. It's very hard to find cohort-type labor stats at a large level among the typical wage and unemployment indexes. BLS does have the NLS study [1], but it doesn't quite cover the right things. Mostly what you get is individual stories like [2], which add up to a picture that at least many people believe, even if it isn't 100% true.
