The more likely explanation for your not having experienced it yourself is that the numbers cited are bordering on silly. Millennials and Gen Z make up roughly 20% each of the population of the US [1], so something like 6 million each. The “study” polled roughly 1000 people. Drawing any conclusions at that sample size is pretty spurious, and even then, the percentages that agreed with the headline are in the 20 and 30% range.
