Same, no. But in a reasonable reference frame, "evenly developed", probably. I think the point made is that obviously the whole "freedom of movement" concept didn't come as a trick to "dump bluecollar workforce into richer economies so that wages don't go up".
Even assuming this was the sole purpose of it today (an extremely ignorant opinion if you ask me, and one that I don't see being backed by OP with evidence) it still doesn't prove that that's what "freedom of movement" is for. At best it would show that that's what it became.
It's more or less like saying that cars are for polluting the environment. They may or may not pollute but certainly that's not their defining trait, rather just a side-effect.
Unfortunately much of the population commenting here was born in a "freedom of movement" environment as such they have very little personal experience with its benefits for anyone. They did however read an article in the Sun once.
