Let us forget that "fact."

"the Australian Royal Commission into Institutional Responses to Child Sexual Abuse found that the average time it took between a victim of Catholic sexual abuse being abused and reporting it, or seeking redress, is 33 years."

IOW, the abuse that was brought to light started many years earlier. If it was news in 1980, it probably happened in the 1940s. While that is the figure in Australia, there isnt much reason to think it was different elsewhere. The accusations against Maciel in the 90s were for abuse in the 50s, though there is evidence of later abuse. It simply isnt true that abuse began with the generation ordained in the '60s, it is closer to the truth that it began coming to light with that generation.
