Poland made many good decisions in the last 20 years - I do not dispute this.

However had, it also is still a net EU subsidized country:

In fact, Poland gets the most money. So, before we can evaluate the net worth, this number would have to be deducted, which would instantly make Poland drop more than 5 ranks in that chart if you look at it. Just compare the numbers for yourself, the calculation is trivial to do.

Here is total GDP per country:

(You have to compare the same year of course; my calculation above is for the year 2024. Poland is now ranked higher than in 2024, but the net subsidies still are given in. Those "Poland is now rich" never take that into account.)
