BOSTON, Massachusetts — The outcome of the United States presidential election last week was more of a Democratic loss than a triumph for Donald Trump. The Democrats lost not because President Joe Biden stayed in the race too long and not because Kamala Harris is unqualified but because they have been losing workers and failed to win them back.

The party ceased to be a home for American workers long ago, owing to its support for digital disruption, globalization, large immigrant inflows and 'woke' ideas. Nowadays, those most likely to vote for Democrats are the highly educated, not manual workers. In the US, as elsewhere, democracy will suffer if the center-left does not become more pro-worker.
