labor and union fees

the Labor party was formed in 1891 from a union
Ever since then they have become the mouthpiece for the left
Most people don't like unions except rat bags I reckon
So how come left wing views are so popular?
Union fees
I reckon it is because union fees are being used to perpetuate left wing views.
I was listening to high school dropout and the awu boss, Paul Howes and he was saying that they contribute to the Labor party and in return they expect to have a say in how the party is run and what it stands for
I have worked overseas for most of my life.
Just wondering are union fees compulsory here?
If they are it may confirm a belief I have that the union fees are behind the popularity of Labor party.
Basically unions perpetuate their left wing views using propaganda and funding for spreading that propaganda comes from union fees.
