It looks like Decades of Astroglide have gotten them Nowhere

It’s the common market that isn’t.

For a large part of European societies, workforce immigration means lower wages, loss of work by fellow citizens, and creates a welfare burden. And yet Europe remains an area of very low worker mobility. Only 2.3 percent of Europeans live in a country other than the country of their ethnicity. Any significant change in this regard would require coordinating insurance systems or worker rights, transferring pension privileges, as well as fully recognising foreign professional qualifications.

Not to mention non-iteroperable medical coverage, the lack of integration despite the scale of intermarriage, etc.

It also can’t write:

Although you can you the same wall tiles, cheeses, shoes or cars all over the EU, the ‘common market’ remains common chiefly on paper.

They do share a common delusion, though:

There is no hiding the fact that the common market creates, temporarily at least, winners and losers, and that member states try various ways to support the latter through welfare policy. But income redistribution will not eliminate tensions between market integration and social goals.

No, but success and growth can. Remember what THAT was like?
