Yes, unfortunately, by virtue of being under the German umbrella he was able to flee unhindered like a rat from a ship to escape Poland more than a year before his party was swept up in the elections.
Fortunately, the most important assets despite his desire to sell them remained in state hands.
With that said, there is a difference with what Tusk did and the Russians did, he did not create oligarchs, but gave them away to foreign, mainly German ones. And he sold them cheaper than he could, what with the combination of the sudden jump in the fortunes of people from his party one can guess where the rest of the amount from the sale is.
Which, of course, is much worse, if he sold to our oligarchs it would be half poor. The money would somehow stay in Poland, and yes the property losses from this are as bad as if we were a post-colonial state.
