It is, but that
in itself isn't a bad thing, because it's bilateral, so as long as the countries with free movement are similar enough there's no mass movement of people.
The argument recently is that people in the newest additions in Eastern Europe are being drawn to wealthier countries
without the reciprocal movement (there are some reasons to move to e.g. Croatia, but for most they're not that compelling). We have seen some, but nowhere near the extent that was "predicted" by UKIP:

So unless kippers can reconcile "it's the Eastern Europeans!" with the fact that it's not, all this chatter about "uncontrolled migration from Eastern Europe" is crap. Or are ukippers suggesting Italian immigrants are taking our jerbs now?
D.P. has been over this fallacy to death. The point is that immigrants don't just come and "eat" - to use your metaphor they actually come and start working in the kitchen
(they contribute more to society than they take in public services).
