Many (especially Germans) try to wrap it falsely as charity and throwing numbers without context.

It is not true for the entire EU budget: the 2014–2020 MFF allowed up to €959.99bn in commitments, so Poland’s €77.6bn cohesion allocation was about 8.1% of the whole EU long-term budget.

For context this is like 0.7% of yearly German overall public expenditure go to Poland. And this money per year is also like 5% of state budget spending.

a big share of this money goes back to foreign companies in form of sales and contracts.
