If the labor werent cheaply and alternatively available, they would have less leverage to do that and would have to pay the market rates for those able and willing to do it for that living wage.
The more people that live here, the more expensive it gets and the less labor is able to demand for compensation and also even just the most basic of employment and services like health and childcare or things like housing.
There has been deliberate efforts to pump up the cost of living and tax base without actually sufficiently funding and providing the appropriate corresponding increase in availabillity and limiting the additional costs that otherwise cuts accessabillity to ensure everything remains in balance to adapt to the influx
Edit: oh no, DOWNVOTES, the kryptonite to basic logic and economicss. Ehatever shall I do
