His "Real World" is the world of high finance and making money. Board rooms, Conferences, and Dinner Parties.
But Jamie's Real World is not the actual world of 3/4 of the rest of the people in the world, not to mention 99.9% of all the other sentient creatures on this planet.
He's sooooo F'ing lucky, but doesn't seem to realize it, like most of the people that inhabit his bubble of bought reality.
I'm not jealous, but if you asked where his food came from, how he thought most people lived or what opportunities they had to improve their lives, or why they can't make the same decisions he and his buddies can without becoming homeless, he'd either not have a clue, or he'd avoid answering the question because his answers would prove what a useless, hypocritical, selfish, lucky bastard he and his class are.
Only good for making money. And that's his entire world; making or collecting something transitory and dependent on "vibe" as value for trading to get an actual thing or service.
You can't eat money, money makes shitty building material or covering, especially electronic funds; coin can at least be melted down and turned into metal and paper money can be burned or turned into a fabric or something similar.
He's really, a sad, sorry, trapped man who depends on illusion and his bubble to survive. If he had to really work through a variety of setbacks or if he had a talent for anything else, he might realize his "Real World" is a small power balancing act in the greater scheme of the World in general.
