Unfortunately these kinds of shitty recruiters and companies will always be around - none of them are thinking about lofty societal goods like family or what happens 40 years later, they are thinking about how to get the most work for the lowest price for their company. As long as droves of young people continue to flock to tech to try and get their share of the money, hiring is a buyers market. Throwing out old people or young people who dare to demand work-life balance will remain a viable strategy for the buyers and many will do just that.
