I think the fact is we could have trained enough nurses doctors , bit like engineering we could've incentivised apprenticeships better , I'm surrounded with Indian engineers or you'll have a french company flooding a job with Slovakian labour. It seems like madness. Romania for example loses most of its professional work force to foreign countries , which is globalisation at work. Worse still is the lower skilled jobs that literally empty towns and villages of mostly men but sometimes both parents , leaving a village with just grandparents and children . It's common throughout Eastern Europe.
