People just finally saw through the lie that the "American Dream" is: Yes, anyone can win. But not everyone. It's like the lottery.
Plus, the "rules" of the game have changed. It used to be "have an idea, work for it, follow it and in the end, with some luck and hard work, you will be successful!". That was the dream. And that even worked. Yes, for some. Not all. Of course, for every single one that succeeded, there were hundreds that failed. But that one success story kept the dream alive.
Today, it's over. The internet managed to keep it rolling for a bit longer than it would have originally and you have a few more of those "rags-to-riches" stories... only that the successful ones were not in rags by any stretch of the word to begin with. But outside those few stories, there is no chance for anyone to succeed. Corporations have the field divided, and there is NO chance for you to become more than a bit player. Ever. The absolute best you may possibly hope for is that you found an area where it's cheaper to simply buy you away than to entangle you in enough red tape that you willingly hand over your stuff.
The new american dream is simply playing the lottery. Same chance of success with less effort. And it's the same game: Anyone can win. Just not everyone.
