When you make an argument for companies paying that much, you are essentially saying "FAANG companies with lots of cash reserves should overpay new hires in the goal to attract as many of them as possible in hopes that a few of them make something profitable and offset the cost"

While a viable business strategy, from a personal value perspective, if you are an average CS college grad, you are by far not going contribute even close to $150k/year worth of value - you are going to do some menial basic code modifications.

So by all means, while you can go and take advantage of the inflated salaries to maximize your own profit as much as you can, but you cannot claim that $150k starting salary is too low.
