I guarantee that the ADA works for whoever is the biggest source of revenue, and thus the biggest funder of executive salaries.
That's just how it is in a system of hierarchical organizations. The executive positions inevitably come to be held by people who have come to hold those positions because they were the most willing and able to do absolutely whatever it takes to fight and claw and scheme and backstab their way into them. And those people not only aren't inclined to serve any interest other than their own - they necessarily aren't even equipped to. If they had any actual integrity, decency or empathy, they wouldn't have been able to do everything they did to win the competition for the position they now hold, and it would've gone to some other scheming, manipulating, self-serving psychopath.
And thus, we end up with something like this. Inevitably.
