hard work with little reward
It has been clear that they will not be rewarded for hard work. It will drive down their GPAs. It will mean, while they are attending university, a losing trade-off between their work to pay the tuition an fees vs. the work on the classes.
It will mean a "career" that will last an average of 15 years or less, while the rewards during those 10-15 years are likely to be less than the expenses while they're in university, let alone provide them the wherewithal to survive an 80 year life expectancy at birth without long periods of extreme poverty.
For the last 25 years, tech execs have been teaching children that, even if they are gifted or even geniuses, they need to look elsewhere for the prospect of prosperity.
