Okay, so as a cab driver I have a lot of opportunities to get frustrated with how selfish and myopic people are. But you know what happens when I do that? I make myself miserable.
I, personally, find that my mental state is much, much better the more I'm willing to accept people not doing things 'the right way'. Yes, I could get annoyed for the hypothetical people who might encounter an obstacle to their mobility here (who have not and may not ever arrive), but what will that actually do for me or for anyone else?
Unless I'm actually moving the obstacle my disapproval is completely useless. It may even cause me to do something stupid and inconsiderate myself as I become distracted by my annoyance.
But if I just let it go, smile, and move on, the utter insignificance of the action can just fade into the background and not make itself part of my focus on how to reflect on humanity or my day.
Literally money. More specifically, the financial need under a capitalist system for businesses to constantly grow and increase profits, and to focus on shareholder profits over making a good product. Most businesses on any sort of large scale today aren't in it to do a good job at making whatever it is they make, they're in it to make money. Their actual 'business' is just an incidental stop on the way to making more money.
You see this literally everywhere. Remember Odwalla? They made these great, super-thick bottled smoothy-like juices. Easily the healthiest thing you could find to drink in most of the places they were sold. Then Coca-Cola bought them out, changed the name to Naked Juice, and watered them all down. What we have now, as a result, is a pale imitation of what we once had.
Why? Because Odwalla was profitable, so it was profitable for Coca-cola to buy up a competitor for shelf space. But once they were bought up, there's no incentive to deliver the same quality of product. They have no remaining competition, so they can release a shittier version and we'll basically just suck it up because it's still healthier than soda.
Our reward for worshiping currency is for everything ever made out of love of a craft or an art to be exploited and turned into a shittier version of itself.
The solution, to my reckoning, is to start making things you love because you love to make them and to refuse to sell out when they come knocking.
