As I have said before, many times. I don't hate all unions.
I don't look for the union label, but if I see it, I'm not buying it. I would rather my money support American made products that are made by non-union companies. Just as I would rather purchase from a local true-value hardware store instead of Lowes or Home Depot. Or a local merchant as opposed to a big-box store.
I have friends who are business owners, I am very sympathetic to their plight. Having a group of employees collectively bargain to demand higher wages than a true free market would command is not something I wish to support.
Why would I want to move somewhere where slavery is legal? I'm perfectly okay with paying somebody what the job is worth, not what someone tells me I have to pay them.
