Joking about what? That my life is privileged? Of course it is.
I'm in my early 30's, employed to do something I love (and happen to think is reasonably worthwhile) at a level more senior to that which I would be employed at in the UK. I earn 6 figures and work school hours. My DC are getting a great education, we live in a big house with a pool and lots of help. I am able to indulge my hobbies, such as riding and have set up a local chapter of a UK charity extremely close to my heart, because living here gives me the time to invest in it.
We dont keep any assets here (although i dont see that as a bad thing
) apart from a car that we own. My DH's car is a company one. If we had to leave then we would be disappointed but as things currently stand we could survive on either of our salaries so hopefully when we leave will be at a time of our choosing. When that time comes we will return to our family home, the mortgage on which is almost paid off. We will both return to the UK better qualified and with more relevant work experience than we left with.
Most expats I know have kept close ties with their home countries, returning frequently and own property there, worse case scenario is you return to the life you were living before you left. I'm certainly not suggesting you or anyone is "jealous" but I would be foolish to deny that I have a good life and that makes me an easy target for that great British sport of being taken down a peg or two.
