Personally, I feel like most of the problems in the modern world come down to issues of scaling. We evolved our brains to coordinate in small bands of people, but we try use those same brains to coordinate groups of hundreds of millions.

The larger an organization (corporation, government, npo, etc.) gets, the worse they get at coordinating around a central goal or set of values, and the more likely they are to evolutionarily optimize around something entirely divorced from the values of any individual member.

A company of 100 employees is entirely capable of creating a high-quality product, compensating their workers well, and avoiding anti-consumer practices. This doesn't mean they'll always do this, but it's possible. Meanwhile, a multinational corporation of millions of people, even if run by the most ethical CEO on earth, will always gravitate toward maximizing profit at the expense of everything else. Even libertarians recognize this as a fundamental flaw in unchecked Capitalism.

Similarly, a government of a few thousand people can create a good constitution for an orderly society, but in a massive government of a country of 300 million people, trying to make any sort of effective, positive political change is borderline-impossible because everyone has different goals that gridlock each other. Even proponents of large government recognize this.

It's tempting to believe in some sort of easy action that could fix this, but truth be told, I think any simple solution would be horrifying, and I think any good solution is going to take an incredible amount of thought and be more complex than the sort of thing you'd see every day on the internet.
