What you are asking and describing is happening right now. In some places around the world the industry is already an unsustainable shit-show, which offers zero financial incentive to a CS undergrad. Some such countries are Japan, Germany and Hungary.
The working hours are extremely long!!! You have to work 60 hours or more most of the time, but managers will try to sell it as a big plus (like, look you can go to all these flashy conferences and you can have kicker table + free buffet, you just have to work hard in exchange) even in face of concrete evidence that the industry in large is to the detriment of your well-being mentally and physically. This management technique is also called stick and carrot.
Also there is real age discrimination. Especially in startups. So it's really difficult to get work-life balance if your life does not revolve around the actual business that your company is doing.
If you can put up with all this shit, and you can save enough money let's say in 10 years so that you can quit, then it might be a good idea to pursue this kind of "career". But again, what kind of career is that sets it's goal as quitting in a reasonably short time.
Salary-wise your payment is gonna be slightly higher then let's say a simple journalist, accountant or let's say an average salesman, but not that great, and because of the long unpaid overtime you will basically get a quite low amortized salary.
