On the one hand, yes; on the other, this understates the impact that had.
My uncle moved from the UK to Australia because, I'm told*, he didn't like his mum and travel was so expensive that he assumed they'd never meet again. My first trip abroad… I'm not 100% sure how old I was, but it must have been between age 6 and 10, was my gran (his mum) paying for herself, for both my parents, and for me, to fly to Singapore, then on to various locations in Australia including my uncle, and back via Thailand, on her pension.
That was a gap of around one and a half generations.
