When the top rate of tax in France 70% odd and i think they have an asset tax as well, I can't see how being French registered would help avoid tax. It's why Gerard Depardue is now Russian
Australia has double the rate of immigration because it chooses to. The Oz governmant, as elected by the people of Oz, has decided it needs more workers. It has then assessed and decided that each of them should be allowed in. The same an Non-EU immigration to the UK.
EU immigration is uncontrolled and we have been told we must accept anyone that wants to come. It is a somewhat different situation.
Also, if you wish to go and live in Norway or Switzerland then you do need a visa (Switzerland) to stay past 3 months or show you are able to support yourself (if not in work) after 6 months (Norway). If you don't have a job, or are unable to support yourself financially, then they can remove you. Remain seem to gloss over this in their "they have to accept free movement of labour" spiel.
Housing - would there be a shortage if we didn't have 300K-500K (depending who's figures you believe) extra people coming each year? Shelter reckon on 250K homes needed each year - net migration is 250K (migration watch 2010 - 2015, not sure if this accurate as the NI numbers show a lot more).
The WTO trade regulations would be more accurate for the point you're trying to make. The single market is agreement between all the signatories on how to play (so in your example all using two goalies). Why do we need a political union to have free trade? Canada has manged it with EU, Switzerland has and so have many others. We have little say in the "rules" now - let me know how the CAP reform or the moving the thing Strasbourg for two weeks has gone.
So's the EU - that's why the accounts haven't been signed off, with out qualifications (4.8% of it's budget "lost" in 2012 for example), for a long time...
You'll be claiming the EU give us cheap roaming costs (it didn't - it was a result of pressure from the ITUG, OECD, ITU, and WTO since 1999. In fact the EU was one of the last places to do it) and protects workers rights next....
