That paved the way for the industrial revolution, the mass armies needed for major wars, and the modern states. It's kind of hard to discuss current state of the world without that knowledge.
Thus most food in Europe is produced by industrial farming - using machines - not indentured servants. Basically if less than 2% of the population can produce the food for more than 100% it makes sense that those 2% are as efficient as possible, not using indentured servants.
There are still some minor food-categories being farmed in less efficient ways (but robots picking e.g. apples/wine-grapes are getting better); that is usually seasonal labor and in some cases people from e.g. Asia are flown in for that - and leave after the season.
Seasonal labour is by definition seasonal, and thus there is no need to import people permanently - and still Portugal is more suited for that than Germany. Portugal has actually been in the news wanting a larger part of the asylum-seekers re-distributed within EU - to work in their farms, but last I checked the asylum-seekers were unwilling to go to Portugal where there are farm-jobs waiting. (And that is still just a couple of thousands, not a million.)
(There are some other work-categories that people claim there are actually "indentured servants" working their backs off in EU; but the majority of asylum-seekers are a bad fit for those jobs.)

So, cheap labour to produce food is one of the worst explanations for the German immigration.
