I just think production machinery should be properly lubricated. You types always talk about it seizing.

So they should just be made responsible for tens of thousands of dollars worth of equipment because they worked there for a week.

It's not a prerequisite. It's just an option that's available to anyone who wants to own part of a publicly traded company. If you want to own it in the traditional sense go be a tradie plenty of tradies run their own operations.

I think thats for the following reasons. Because the c manager understands the value of investment long term and they believe they can impact the company in a positive way. They also likely have more disposable income.

A factory line worker has very little control over the performance of the company. He wants his weekly pay to be in full cash and that's it because he either has less disposable income or doesnt understand the value of investment.

If the line worker wants to invest he would likely invest in another company than his own unless his company was preforming exceptionally well.
