Corporation don't pay taxes really anyways, because
Because they've bought off politicians to give them enough exemptions and loopholes so that, on top of low tax rates, they effectively pay nothing.
2. Costs get passed down into first-order (consumer) goods for the most part anyways
All prices area always set to maximize revenues. If companies could arbitrarily charge more money without losing more customers than they made in new profits, they wouldn't wait for new taxes or wage increases to do so. They would just do it and pocket the profits.
Additionally the. U.S has an absurdly high top corporate rate
Zombie talking point. No, it's not high to begin with, and there are enough loopholes and write-offs that the richest corporations in the world pay little to no taxes.
Public sector compensation is already quite generous
"Citizens against government waste". Why not go all-out and cite Grover Norquist and Ayn Rand?
Most of what you mention is just sort of normal compensation and can be negotiated individually as appropriate
Individually you are irrelevant and completely expendable. As part of a collective labor force, you are not. You know this.
as it makes it difficult of impossible to remove low-performers and inappropriate behaviors
Another zombie talking point. You guys really think that once you'd join a union, you'd really stand around and think "boy, I wish Bob would start slacking off so I can do my job plus his!" And there is nothing about unions that prevents people from being fired with cause.
This due process thing is precisely what a lot of the best and brightest in the public sector object to
Now you're just putting on the clown shoes. The employer having to actually give a reason for termination is objectionable to no one but employers.
Why should someone be forced to support a group that advocates for policies they think are harmful or unnecessary in order to keep their job?
Zombie talking point #3. Union members are free to vote on what policies their union supports. Employees that work for a Koch Industries subsidiary have no say whatsoever over what Charles and David do with the wealth generated from their labor. Why do you hate democracy while loving aristocracy?
What you call freeloading, is just a pejorative term applied to a positive externality.
Hand waving. Why, exactly, should workers enjoy benefits won by a union that they did nothing to earn? Why don't you try stopping by your local chamber of commerce, and tell them you want all the benefits of membership without paying a cent in dues.
Unions pushed for the eight hour workday and made it the norm, but does every worker with a 8-hour day ow the Wobblies a union due?
If the company had previously been demanding 14 hour workdays and paying employees in company script? Then yes, they did owe the union. Any more questions?
