Because wages are high and the more high wage workers the higher rents will generally be
Capitalist class wants to break even with the labor aristocracy. "Luxury" or "good neighborhood" rents, which drive up rents in proximity (and across the metro eventually), are used to get as much out of that big paycheck as possible.
If your city is attracting a lot of 6 figure jobs your housing costs are gonna jump, why? Because that was the purpose of the city "attracting" such jobs through, first "slum clearance" (oppressed removal) -- then subsidies for things like hospitals and tech (or university expansion) to bring in workers that don't mind paying thousands in rent so that the propertied classes can make a lot of money.
Even a new Amazon facility because, while the jobs aren't 6 figures, they are usually much better paying than minimum wage and will also raise rents in the lower sector as the community now has more money flowing through it so the petty bourgs and capitalists want to get those dollars at the end of the month and raise the cost of living to reap all that new cash.
There's more to be said about how these high wages are funded and the clue is in the number of workers in the periphery with impoverished conditions making clothes and gadgets for 1/10th to 1/100th of US minimum wage and where post-Soviet resource wealth is going.
