That's a bit harsh.
The company knows what it's doing. Employees often don't. And in tech, there are no unions or widely-subscribed (and non-employer dominated) professional organizations to push back.
As Adam Smith notes in his Wealth of Nations (book one, chapter 8):
What are the common wages of labour, depends everywhere upon the contract usually made between those two parties, whose interests are by no means the same. The workmen desire to get as much, the masters to give as little, as possible. The former are disposed to combine in order to raise, the latter in order to lower, the wages of labour.
It is not, however, difficult to foresee which of the two parties must, upon all ordinary occasions, have the advantage in the dispute, and force the other into a compliance with their terms. The masters, being fewer in number, can combine much more easily
There's a reason unions exist, and even more reason why companies and their owners fear them.
