That's pretty much every employer ever in our economic system. Your labor force is a necessary evil and means to an end in far too many business leaders' minds. Any way they can reduce labor cost, the better, unfortunately they have to tiptoe around laws to do it and invent new clever approaches to achieve the same ultimate goal: labor rights and wage supression.
It's not just businesses though who are employers. If you've ever hired someone to do a contract job for you, say a plumber, electrician or some other small construction project, you probably thought about and devised all sorts of ways to reduce the time and material costs of their efforts to save you money. I see this happen with a lot of people. Our culture has a deep seated disregard for other humans when money is involved. For those who can easily afford the cost, I don't understand. For those who have to pay someone out of necessity but can't really afford the costs, I understand.
Successful businesses fall into the former category. They are not charities, they have a profit motive and margin so they can afford it otherwise they have a failing business model. It all becomes a matter of how much success of that model they want to share with those who make their model possible and how entitled they feel in deserving of reward for their models success. To me, a lot of it is sheer coincidence and luck. I say you should contribute back to those who enable and make you successful. It's all about balance though, again, a business (well, most) isn't a charity and its reasonable to expect them to garner rewards for their efforts and success, whether it be luck or innovation and hard work based. A business also shouldn't be on the other extreme operating as a sweat shop driving down others rights to benefit those in charge.
There's a healthy balance somewhere in between and many captains of industry or investors holding the purse strings seem to have forgotten this. In addition, hyper competitive markets have forced these sort of optimizations. If you take two identical businesses with identical cost structures, products, etc and one decides to better compete and lower costs to consumers, they can reduce their labor costs, then other participants in the market will have to follow suit to remain competitive or fail in a low cost driven society. So even if you understand the value of people and want to share the wealth, it would be quite difficult.
The way to protect against this is through baseline legislation like minimum wage, overtime limits, etc. When all competitors in a market have to comply or be fined a cost with too high of risk (the punishments for violation need to be high to dissuade abuse), it's not possible to undercut your competitors in these aspects because you can't optimize beyond these constraints. We need more robust labor laws and enforcement to fix this issue, IMO. Let businesses optimize outside of labor because labor is already incredibly optimized as is and will only reduce quality of life for most if it continues the ongoing trend.
