Just a thought really, nothing contentious.
Aside from the unknown emotional drama that comes from Migrating (missing family, Friends, etc which you cannot foresee or underestimate), is it easier to migrate these days, here's why ?
Nearly everyone has email, sending instant letters and pictures via e-mail is a great way of sharing, just think of the older days when letters would take weeks to get a reply.
Facebook is another great way of keeping in touch, sharing pictures, locations and thoughts.
Calls home are soo cheap these days, by so many methods, Even just 10 years ago it would have been a min 50c per minute, these days you can't spend that in 1 hour.
Video calls via Messenger too, to see family and friends
And finally, although still expensive flights are relatively cheaper to the old days, my aunt migrated some years ago, and if someone was to visit england it may be a choice of who could go rather than when they could all go back.
then to help you settle there are shops to give you foods from home, more pubs do british foods and beers, supermarkets now do microwavable curries, plus loads of things that have changed even in the 7 years I have been here which seem to make it easier.....
But........ With all this ease of keeping touch, helping you settle, does it actually have a detrimental effect, of keeping us with one foot in the British camp....
