Well if you paid more tax the government would have had more to squander on the government jet, tunnels that aren't big enough, luas transport that hasn't the capacity, or Hanifan to have as another benefit / bonus / pay raise etc etc etc.
If you want to make a contribution write a tax deductable donation to Our Lady's Hospital in Crumlin that's closing it's wards to genuinely sick children. Or perhaps to your local GAA Club as another example.
Don't worry about not paying taxes to the revenue. If you're up then good for you. When you see a just government then maybe I'd think different. I hate to come accross as a scammer myself but I can't tell you how it makes my heart sink to think about the BILLIONS squandered by the politicians and the ignorant greedy electorate that didn't care less so long as they had their piles of consumerism. We have no infrastructure from all that money, there is not constructive thinking that will lead us out of this recession other than more tax on the little guy that would be you too if it wasn't for the cute angle you have going.
Good luck!
