Do buybacks cause profits to increase? Maybe from what I can see? But long-term? If all we care about is short-term then that will lead to the continued financial cannibalization of the US economy. Where private equity firms buy companies and destroy them for short-term profit while loading them with the debt used to buy them.
I think the obvious answer to both these questions is: no. CEO pay and buybacks don't focus on profits. At best short-term. Which isn't good.
I think companies should focus on making good products that positively serve the countries they sell in, while secondly still aiming for a profit.
