Well that’s just nonsense. I guess if we are going to just spout nonsense then I’ll need to start pulling my weight.
There is no human caused climate change.
Vaccines cause autism.
Governments and pharmaceutical companies are withholding the cure for cancer.
Israel isn’t a genocidal apartheid state.

This argument doesn’t make any logical sense.
Your argument appears to be:
Some labour unions are bad/corrupt, therefore no trade unions should not exist.
You seem to acknowledge that some governments are bad/corrupt, but don’t apply the same logic to them. If the same logic was used it would be:
Some governments are bad/corrupt, therefore they should not exist.
However you instead apply the logic of:
Some governments are bad/corrupt, but they should still exist.
I just want some logical consistency.
I’m not arguing that there aren’t bad labour unions who don’t effectively represent their members. I’m arguing that the existence of bad/corrupt labour unions does not mean that labour unions should not exist at all.
