Striving to make it in the "best" place, while shitting on less-hyped places as beneath your consideration...this strategy is useless for those who are not top 20% in looks, affluence, or charisma. Choosing to associate only with the "best" people, rejecting your low-value friends and family members is not a recipe for happiness either. Stuff your face with the "best" food 24/7, and chances are you'll feel perpetually glutted and dissatisfied. Eating oatmeal for breakfast allows you to properly enjoy the king crab for dinner.
What happens in these fiercely competitive places is you either get fucked with by fake friends who try to parasitize your energy for their benefit, or you get cast aside as too low-value to be worthy of anyone's time and attention.Everyone wants to live in L.A., but what percentage of people who move to L.A. from podunk nowhere ever get to live their dream of social preeminence? A tiny minority.
Americans move to desirable regions of their country more than people of any other nation. This is why so much of America's populated places are affluent, bustling, soulless wastelands. So many Americans feel like they don't belong anywhere, they use drugs more than any other country, they suffer from social isolation. They are stuck working to pay banks and landlords because most families don't stick together and slowly accumulate resources, generation after generation.
This is what happens when people fall for the bullshit lines: "You deserve better than this life, in this town, with these people. You'll have so much more fun doing your own thing in your own place far away from anyone you know." Of course, if you've already bought into the lie and thrown away what you had, you might as well join the herd of restless travelers chasing greener pastures beyond the horizon.
