What makes me laugh about this thread is the way that high earners think they are uniquely talented and irreplaceable.
I was a high earner. You are likely talented and hardworking, but you are also lucky and replaceable. If you go, there may be gnashing of teeth for all of three months before you are replaced and the ripples of your existence ate gone.
For every one of you, there are ten champing at your heels to take over if you go.
That's the whole point of the unlimited skilled visa migration the Tories have implemented to let in 1.2 million people per year.
You didn't create wealth, you sold your skills in a marketplace that existed before you and will exist once you are gone.
Meanwhile, other people clean your offices and hones, edycate your children, look after your elderly and sick,. These other people take your rubbish away, grow your food, pave the roads you drive on, provide the energy you use and the water you drink.
You are not an isolated island of brilliance and uniqueness. You are part of a completely interdependent society. Your skills are marketable right now and sell for a high price. If your industry goes pop or your skills become obsolete, you may find yourself on the other side of the street, reliant on healthcare or other services.
This idea of international shipping for tax benefits. You can move to the Middle East where they are riding an oil boom. But apart from that, you will be lucky to get a lower tax rate in Europe, and you'll be lucky to get a visa for the "New World" like the USA.
But honestly, you don't scare me with your "threats". Please do leave, taking your entitled, selfish attitude with you. You're not the sort of person we need in this country where our wealth is becoming more unequal by the year. We need grafters, not spoilt children.
