Representatives are a function of the electorate. If you want better representation, not only must people run, but the electorate must turn over (old ideas and their voters dying out, new voters and their ideas aging in). 1.8M voters over the age of 55 die every year, 4 million voters turn 18. Worker rights support increases as cohort age declines (and skews progressive, naturally).

Certainly, a long term fix that will take decades. Near term, gotta organize, which can be done today. And workers need help today.
