You're missing what is clearly obvious to everyone else.
As a NY'er, where the real estate game is laid out in bold, let me explain: it's a pincer formation.
They flood with zone with 'new nikkas', don't really matter who, preferably with as few rights as possible. Upend the labor market by hiring them cheaply en masse (thereby lowering wages overall, broke wp suffer here too). Make them feel special ("they're such hard workers") to increase the divide,- why not? it's free programming- but at the same time, keep them desperate. This is key because it keeps them malleable and open to any suggestion. Market forces do the rest. Prices go up on everything. All of a sudden, no one can afford to live here anymore, gotta go.
Note: this scenario occurs with or without the firebombing. But the firebombing is egregious, you have to at least admit that.
