Nothing in this world is free. The US tax rate isn't high. The issue is, you don't get a good value back.
You can't have strong unions without money for unions.
Organizing people costs money.
Union dues tend to be in the $10-50 per month range, while unions easily increase wages by hundreds a month through collective bargaining.
Most of the unions costs are fixed, so if everyone is a member the average due can easily be on the lower end ($10-20).
If you have a problem with that, then that's exactly why you don't have strong unions.
If vandalism continues, then this will easily be the death of Tesla.
Nobody will want to buy a Tesla when an equivalent Mercedes has half the insurance rate.
Boycotts also hurt Tesla, but vandalism will be their death.
