You guise are taking shiny baubles for Manhattan
Isn't Manhattan the shiniest among all baubles?
Well indeed. Thats why when the cleverer, richer, stronger people turn up - who can see that and are necessary to help build it - you'll regret trading them the most glittering future for a tawdry game show prize or a used Mercedes.
Some trade is necessary, of course: pizzas and space trips to show that it's functional and redeemable, but they're statements. Being able to resist near-term temptations for long-term gain is what makes us intelligent animals. You don't eat your seeds if you're just peckish.
