As far as it relates to my actual comments - I have said I did not supported it then, I don't support it now - you can believe it or not but the change in the prosperity did not influence my viewpoint. It could have influenced the government - but it is hard to tell as I don't know their foreign policy on that and I don't care tbh.
If Poland will be reaping the same kind of benefits from EU unrelated to the EU funds - I won't mind being a net payer as PL will be still a "net winner" in other aspects as WE countries are currently. Maybe DE , FR along with NL won't try to torpedo other PL industries (as they did with logistics / transport one) we can achieve that.
Obviously - politicians will still probably try to spin PL being a "net payer" against "net recepients" in other EU countries - that's just "political free real estate" and they don't have to address the fact that the "economy" benefit goes mostly to the pockets of big companies and the wealthiest - so it's beneficial to set population on population and make people to look down on one another.
