then Poland can become a very tempting choice particularly since it hasn't yet adopted the Euro but will remain a EU member.
Poland is not a tempting choice for anyone in banking or insurance. At least two medium sized banks were put up for sale as a result of the bank tax, and further consolidation is likely. Anyone involved in finance is going to steer clear of Poland for the simple reason that a 0.44% tax on assets is a tax that doesn't need to be paid elsewhere.
Furthermore, Poland is politically unstable. No-one is going to build serious financial infrastructure in an unstable country.
Markets are global today and many financial institutions already have a presence in other major EU cities like Paris, Frankfurt and of course Warsaw.
You don't seem to understand what made London a financial power to begin with. The regulatory light touch doesn't exist in Paris, Warsaw and Frankfurt. Paris has the infamous French bureaucracy, Warsaw isn't stable and Frankfurt is too honest. London on the other hand is willing to turn a blind eye, knowing that America also has turned a blind eye to the numerous tax havens operated under British jurisdiction.
Furthermore, a lot of the best talent doesn't particularly want to work in Frankfurt, Warsaw or Paris. London has everything - finance is the bedrock, but a lot of real business is done there too, particularly more...interesting deals. None of the other three EU finance centres have such a reputation.
Britain will have all the time in the world but like I said it is a one trick pony and will have nothing to offer when it leaves the EU or if Corbyn gets into power.
You're not very clued up on British politics if you think that Corbyn has any chance of entering government.
As for leaving the EU, it merely means that Britain is in the same place as Zurich.
Politicians don't get popular with the public and their business tax base by being stupid.
You haven't got a clue about the VAT changes that I'm talking about. Either way, this government is not and was never popular with the public, as it only won 19% of the votes of the eligible electorate. Business is rapidly getting frustrated with the anti-business moves of the government, and Morawiecki's plan has been discredited already by the actions of other ministries that want to increase their power/control over private business.
Poles are realistic and prefer to be self-sufficient.
See, it's statements like this that prove that you're thousands of kilometres away. You see, if Poles genuinely preferred to be self-sufficient, why has Poland sold 20 billion złoty worth of debt (mostly to Germany) in the last 6 weeks? The deficit this year is likely to be over 60 billion złoty - that's not self-sufficiency.
Other Poles may see the collapse of Britain as the right time to move back to Poland to start up their own businesses or participate in the growing economy there with the added benefit of raising their children in a true and wholesome Polish environment.
Poles aren't going to come back to a country that's politically unstable, with a very unfriendly business climate and a situation in which the government openly uses hostile methods against any opposition. Furthermore, anyone coming from the UK will take one look at the hideous bureaucracy required to open a limited company and compare it to the UK, in which companies can be established within 20 minutes online.
As for "true and wholesome Polish environment" - don't make me laugh. The corruption and nepotism in Poland at the minute is anything but true and wholesome. Don't forget that Polish farmers are currently waiting for nearly 2 months for their agricultural subsidies that the previous government always paid by the end of December.
Brexit is foolish and short sighted, but the UK has far more clout and power in the EU than Poland will ever have under this current government.
