This article doesn’t provide evidence for your claim that plastics are not so abundant in the oceans, it only points out that a specific study that relied on a false premise (that PVC is a high percentage or is well-represented in ocean plastics) is flawed.

This isn’t at all what people by money not buying happiness. Even if your life objectively improves, it’s just a matter of time until your brain adjusts to the new normal and you’re back to the same levels of happiness you were at before the money. It’s pretty much the crowning “feature” of our biological wiring - because if an animal like us in ancient times was blissfully content the moment their lot in life improved, they would stop trying and not end up spreading their genes. So we’re pretty much doomed to never be truly happy/content because of how natural selection works.
I was going say something to this effect as well, for the other harder drugs I’ve tried. I do remember having fun while on them, but I also vividly remember the “come down”, and don’t really crave them at all because of that. I wonder if this (psychological?) trait is more common amongst people who are unlikely to become addicted to drugs.
