We are still contemplating this ourselves. My husband will be 48 in January. He is a UKC and has lived in the US for 10 years. We have 3 young children together (8, nearly 4 and one that is an infant-- we're late bloomers). At a time when men his age are about to become grandfathers, we have a full nest! Not only do we need to be concerned about retirement, healthcare, mortgage payments, etc. but making a life for our kids as well.
We were going to move back as early as December, but our plans have been moved back to Spring so we can have time for our son to finish up the school year, put money back, and to make sure we aren't jumping into it too soon. Secondly, my husband has been trying to find a job from the US and while there has been a lot of interest in his CV, there is not a solid, confirmed offer on the table. I do not think it is impossible to find a job there at this moment, and it would probably be harder for him to find a job here in a city that boasts that it's "recession-proof." It also helps that you already have your visa and can arrive there and start job-hunting.
I do not think that it is drastic to move at 51 in a recession. We also have been weighing the pros and cons. I would love to get some feedback as well to reassure myself that my husband isn't making a decision on thinking the grass is greener.
What are the advantages/disadvantages of aging in the UK? Retirement? Social services/benefits?
Without going into the finer details yet, I would like to get a general idea of what you think so far.
