These salaries don't come from thin air, they're constrained by the market rate at which engineers can be hired and retained. It's unfairly reductive to say that the engineers aren't contributing value since they work in ads. We work in all sorts of fields from the frivolous, like consumer electronics, to the decidedly less so like self-driving.
If the discrepancy between engineering salaries and research/teaching/nursing salaries is bothersome then perhaps the blame should be placed on the economic environment that has produced this result, not the twenty-somethings that are accepting great compensation.
