There may be lots of people in that category but they're still a relatively small % of the PAYE population. I think the general statement that 99.9% of people will not become wealthy from within the PAYE system is still broadly true. The vast majority of the PAYE population are unlikely to become wealthy solely as a result of their employment.
Latest Revenue figures below for 2021 have only 7.7% of PAYE workers earning over €100k. Given the tax on that and the low spending power here its more a case of surviving and making the most of it rather than really getting wealthy. We may get lucky with our PPR and maybe our pensions if we're in them early and deep enough but our wealth is unlikely to be from earnings within the PAYE system for the vast majority.
