From 2013 onwards. Ireland paid more to the EU than they received, but that ignores they paid nothing to the EU from 1973 to 2013, a period of 40 years.
"The money received was spent on infrastructure and other pillars of economjc growth. By 2020 exports to the EU amounted to a value of approximately €30billion to the Irish economy."
So, like Poland, Ireland was able to grow by using money they had been given by others...
Yes, this is the basic premise of the EEC and the EU - that money generated by others will enable poorer regions to develop - and in time become net contributors when their economies develop...
...as opposed to their own efforts and skills to generate the money in the first place. Spending money provided by others is easy
Your basic problem here is that you don't understand where money on an investment scale in general comes from, what that money is for/ how it can be put to work, and why it was a fundamental function of the EEC and subsequently the EU to spread the wealth of more prosperous members to the poorer regions. There's a very strange and inexplicable adherence to the "I'm alright Jack" school of anti-economic thought evident in your sniping.
The fact that all the constituent parts of the global economy benefit when as many markets as possible are available for manufactured goods, foods, and financial services seems to have gone completely over your head. Everyone benefits when prosperity is spread around. This is economics 101.
You also sound as if you neither know nor understand anything of the way funds are allocated to different countries under various EU programmes. Do you imagine a case of blank cheques written willy-nilly?
Ireland signed up to a common enterprise from which she has benefited greatly, and is now paying to haul others up from their own circumstances born of oppression - a clearcut case of naked self interest, actually, having seen what goes around come around from 1973 on. It's a pity for the UK that that particular observation was never made and instead, in 2016, classic, shortsighted, short termism reigned, even though there was a time when the UK pushed hard for the absorption of poorer and underdeveloped former Eastern Bloc states who would be net recipients of EU funds - like Poland - into the EU.
How did Ireland manage to become a net contributor? By availing of various EEC / EU funds and targeting investment in telecommunications and transport infrastructure, in agriculture, in food / beverage processing and marketing, and above all in education - primary, secondary, and third level, with the development of the Institutes of Technology in particular facilitating the emergence of graduates equipped for employment and leadership in pharmaceuticals, aerospace engineering, IT, software, etc. In other words, strategically, wisely, and with the wellbeing of Irish society at large foremost in mind. In turn, Ireland's foreign aid budget has grown from £2.5million in 1974 to €776.5million in 2023, in hopes that the rising tide can raise as many boats as possible.

Are you as miffed as you should be that this funding is no longer available to British research? Research is a driver of economic progress after all.
