I agree in theory, but I suspect there will be a mass exodus post-Brexit and any Labour government needs to tread very carefully indeed as it is very easy to move money, assets and large businesses to more favourable eonomic climates, and this is where most of the tax-take lies.
Yes and no.
One of the central problems in the UK is wrt real property ownership and exploitation. To the point where the *HMRC* rent buildings which are owned by an 'offshore' company.
Those who 'own wealth' have to do so by some mechanism or other. And as has been discussed elsewhere, what this is based upon varies. So we could choose to limit ownership of property to people who *reside in the UK* or can satisfy some other tests which mean they have to declare their full income and wealth and thus pay tax here like the rest.
We're going to have to deal with the damage our disfunctional property arrangements have been doing anyway. As things stand it is also the main reason housing costs so much.
Similar rules could be applied for those companies who wish to *trade* here.
No system will be perfect. But it isn't beyond the wits of man to ensure that if the rich wish to make a prifit from the UK they have to accept some rules in return. Some will accept that, others not. But the ones who refuse are likely to be the ones who insist on tax dodging - leaving gaps in the market for others who accept not dodging, etc. Quite simply, if someone is tax dodging *now*, then we haven't actually lost anything over that if they booger off and cease being a burden on the rest of us. i.e. we haven't lost more tax. And those who stay 'in' will pay the tax, and work by the same rules as the rest of us.
Similarly the 'private limited partnerships' etc could be legally converted at the wave of an act of parliament into companies that have to declare all the relevant info or be taken over.
The advantage to the owner of real property is that it is, physically real and has useful value which stems from that. The disadvantage for them is that a house or a factory building can't be physically shifted to another company with the wave of a pen without anyone noticing.
So the argument that we can't do everything doesn't mean we can't do anything.
In some way, if the economy tanks because brexit is the last straw, that can be an *opportunity* to make useful changes which suit ordinary people, not an excuse for the rich to gain more power.
Personally I expect another crash anyway. 'Austerity' hasn't fixed any of the real problems, and *private* debts have become large again, spent on consumables rather than invested.
I agree, though, that tactically, it would be best if we can to wait until the wheels drop off with May still 'in charge' (sic).
Merry Xmas.
