Eggs and milk used to be staples people “needed” they were just few alternatives in the food market. Now they are basically luxury goods with staples being things like chicken nuggets and colas.
I’m not saying it’s good or bad either way, but if the price of eggs were increased 1000% it wouldn’t effect people’s quality of life as much as a 1% increase in the cost of education or healthcare.
If your business is operating like this it’s not sustainable. You need 10 developers for every project so the senior developers can complain about meetings instead of exposing themselves to code review. That helps there supposed knowledge.
Senior developer wants job security having an unsupportable project or two doesn’t matter because 99% of the job is stretching deadline to line up with vacations.
