Actually you're wrong too. 51% of workers make less than 30,000.
OK, so let's break this down once and for all using math.
In 2016, there was a total of roughly 130,000,000 votes cast @ a 55.7% turnout. Which means there's roughly 235,000,000 eligible voters.
We also know that income of $30K a year is the 67th percentile of income in the country. So we can extrapolate that of the 235,000,000 eligible voters, roughly 157,450,000 of them have an
income at or below $30K.
According to the unsourced information
Flash provided before, only 40% of those with income below $30K voted in 2016.
So 40% of 157,450,000 eligible voters who make up to $30K a year would be roughly 62,980,000 votes cast by those who make up to $30K a year in the 2016 election.
Now, we know that 60% of the total US population is white, non-hispanic.
And thanks to the unsourced data
Flash provided, we know that 63% of white people with income under $30K voted for Trump.
And also, thanks to the unsourced data
Flash provided, we know that 53% of those in the <$30K percentile voted for Clinton.
So...
62,900,000 voters with income below $30K cast ballots
53% of them cast ballots for Clinton, with 98% of black people voting for her.
BUT
63% of white people voted for Trump, while only 2% of black people voted for him..
So it would definitely seem that the voters Trump got in the <$30K bracket were the white trash voters, and that what powered Clinton in that group were the votes of minorities who, as you said, didn't even reach 50% turnout in that bracket.
That is, if we accept your unsourced numbers.
So poor white trash voting racial resentment would seem to be the same poor white trash killing itself in red states because of poor life choices, lack of ambition, and privilege.
