@hawkeye10,
Those are two separate issues; that most levels of government were not competent enough to live within their means is not the fault of unions. Unions protect workers; without them they would have no power to negotiate wages, benefits, or working conditions. Unions are responsible for most labor laws in existence today. If our country never had unions, I would hate to think what conditions workers would be working in today.
Study about Ceasar Chavez, who organized farm workers, and learn what they were able to accomplish for farm workers.
When my siblings and I were children, we had to work out in the country every summer to earn some money. It was hard work, and there were hardly any protections for farm workers. It's much better today, and all those advances were made because of the farm worker's union.
