With respect, the thread is about that, have a look at the first post again.
To your other points, I have no problem with the Group B/C thresholds being increased as well, again throw it into the calculations with the requirement that the whole thing works out tax revenue neutral.
The purpose is not for Revenue to collect more tax or to collect more tax from the less wealthy, so the thresholds would be restructured to ensure this. Again I’m not sure I understand your objection, unless you’re one of the wealthy individuals using the €3k exemption for the purposes outlined above, you’ll be getting a greater ability to pass on wealth tax free because your allowance is no longer use-it-or-lose-it at a time when most average people don’t have it to give.
This is not a money grab from the rich, it’s correcting something that means the more money you have the less tax you pay.
