Walking to work. It once was good, but no more.
Riding a horse to work. It once was good, but no more.
Taking a carriage to work. It once was good, but no more.
Taking a streetcar to work. It once was good, but no more.
Taking a car to work. It works for now.
Things change. Just because something used to be good, does not mean that it always will be. Someday, some type of mass transit will replace the private car in many areas.
Get a job. Join a Union. It once was good, but no more.
Things change. Unions had a place during the early industrial revolution as workers moved from the field to the factory. Most early factory workers were uneducated and uninformed. Employment laws had not yet caught up with the move from an agrarian rural lifestyle to one based around big, urban employers. Workers needed to band together to protect against unfair and unjust treatment. The Unions worked.
But worker protection is no longer the primary goal of the Unions. Money, politics and control of the worksite are now the most important things to the Union bosses. Unions are the primary tool of the progressive/socialists in achieving their goal of wealth redistribution. The "good of the worker" is merely a campaign slogan to increase the dues co-opted from the membership in order to be able to finance the real objectives of the Union bosses.
Workers are no longer uneducated and uninformed. There are more than enough laws on the books to protect workers today. Unions should be allowed to exists as any other organization is allowed to exist. However, all laws favoring Unions and giving them special powers should be repealed. Just as I pay dues to the NRA and NESA, I can pay dues to a Union if I want to. However, my membership in the NRA has nothing to do with whether I can work for a certain company, and my employer certainly does not have to deduct my NESA dues from my paycheck.
