Poland's successful big business?

Most of Poland's industrial and commercial assets (factories, media, breweries, banks, etc.) have been sold off to foreign capital, often at a steal due to behind-the-scenes finangling. Only a few native Polish ventures have made it. I have heard of Solaris coaches, Polsat and TVN television channels, Marcpol supermarkets, Optimus computers (run out of business by the authorities)...but not much more. O yes, the Kulczyk empire. Anyone know of other major business enterprises based mainly on Polish capital?

Use internet and find more.... Comarch, Orlen, Lotos, PKO BP, Inglot, Reserved, KGHM, PGNiG, PSE, to name a few, not to mention numerous food processing companies.

Many dzięks. How would one google it: Polish-owned assets or what?
BTW, the Tusk grang want to privatise (read: sell off to foreign interests) such induistrial pearls as PGNiG (gas & oil concern) and KGHM (copper mining & metalurgy).

So be it. State ownership of companies generates only corruption. As long as they pay polish taxes the owners can be Martians as well :-)

What makes you think if they would be Polish-owned they would be more efficient/honest ?
What is the difference if KGHM would still be state-owned?
