The decline of the American work ethic

I fully appreciate the hard work that American workers perform, the value of it, and that it should be appropriately compensated.

But now let us look at the UAW strike of 2023.

They want a work week of 32 hours??

Come on. American workers have worked 40 hour weeks for generations.

You want the same pay that was paid to those who worked 40 hour weeks for only working 32 hours per week?

Please explain this.
