My book, Vote Like Me, makes the case that we should create a system for income security that will make unions obsolete.

If a terrible teacher making $50k per year knows he or she can leave and get a new (more appropriate) job making $50k per year, most would be quick to make a change.

If a bad teacher knows they could get fired, they now have incentive to improve their skills.

The current union model should have died a long time ago.
