Helping other professions (esp. white collar ones) to unionize will increase support for unions.

[reformist2]

I think a big reason existing unions get so little support from the public nowadays is jealousy/envy - they don't like seeing unionized workers getting things they don't or can't get.

In a way, I don't blame them. It isn't fair. All workers deserve decent pay, health benefits, pensions.

But just as it's not reasonable for them to want to tear down existing unions, it's also not reasonable for unions to sit idly by and watch other workers be ground into the dirt - unions have to do more outreach, and expand the base of support by encouraging other professions to unionize. Retail workers, grocery store workers, accountants, computer programmers, engineers, even lawyers.
