That was a straight-up heist. But at least there was an actual (close to existential) crisis to justify it.They eroded trust already with the pension levy.
Also, if it really only effects a tiny minority of people, then by simple math, it can't be significant source of tax revenue!
I'm not claiming my maths are right here but as a rough, back of the envelope, calculation
From this quote on RTE.ie ""The number of retired people in Ireland increased by almost a fifth between 2011 and 2016 to 545,407." We can assume 90,901 added over 5 years, so 18,180 per year. But that ignores deaths, so from CSO we had 7,398 deaths in Quarter 4 2020. So assume roughly 29,000 deaths per year, implies roughly 47,000 people retire in Ireland each year. Only half will have private pensions - 23,500
If the 200K limit affects 1% of those it would be 235 people.
If you decrease the limit from 200K to 150K, that would be 20% tax on 50K = 10K
10,000 from 235 people = 2.35 Million which is roughly what the government spent on their fancy new printer.
Now I've made a few assumptions there, so I'm sure the figure is wrong, but ballpark, it's not big money!
