To me, a more fair comparison would be how Amazon requires all office workers to shadow a customer support representative for one week out of each year.
I don't think the OP's suggestion does anything close to reinventing the concept of a worker cooperative.
Amazon really is not a good example of a successful employee management. Their attrition is horrible, worst work life balance culture out of FAANGs, their reputation is horrible and working there is most disliked. They cast a wide net, but lose employees fast.
Have you worked there? I have quite a different experience than this.
I found Amazon's hiring practices and employee management to be very effective compared to other places I've worked. In general, I found their whole dogma really worked in practice, which surprised me at first.
I have not worked there. It is what I hear from other people's experience. Of course it will vary between teams, but the reputation is still low and attrition rate very high.
