Because the Nazis saw them as an inferior race. Although the Poles didn't suffer as much as the Jews, German hatred against Poland was rampant.
Many Wehrmacht units engaged in massacres of Polish civilians during the 1939 September Campaign. Afterwards, the Einsatzgruppen murder squads began the elimination of the Polish elite (scholars, teachers, librarians, professors etc.)
In fact, many Nazi officials sought the extermination of the entire Polish population. SS-Reichfuhrer Heinrich Himmler stated "All Poles will disappear from the earth"
it has long been a tradition that people from a conquered country had to work as slaves for the conquerers. When Poland and other countries were conquered by the Germans, the people were recruited to work as slave laborers in the labor camps and on German farms. It was mostly the young people from conquered countries who had to work for the Germans.
When Poland was conquered by the Germans and the Russians in 1939, the Poles did not surrender or sign an Armistice. The Polish Army escaped and then regrouped as illegal insurgents who continued to fight illegally as partisans in defiance of the 1929 Geneva Convention. When they were captured, they were sent to concentration camps.
Additional comment
It may have been a traditional for the conquerors to use the people but the Germans took the murder and suffering to a new level. Further the people were not recruited but forced.
it was the closest country they could take over and it was going through a depression so they had basically no military so the just surrenderd
All the extermination camps were situated in Poland.
