The 60's were an era of labour shortage in the UK. Recently some British towns had a labour shortage, such as Reading. This means that garbage collection jobs pay well, which is a good thing for those that want to work and be home in time to collect the kids.

A labour market should have people dropping out for having babies, going to education, sickness, looking after elders of the family, going on adventures and self improvement, for example people that want to write their own app/book.
