Mariage a la Mode

Here’s a very interesting report on the BBC claiming that the Conservatives are worried that marriage will become a middle class ‘thing’. If you’ve read your textbook/s you will know that support for marriage - especially but not exclusively - from the Conservative Party is nothing new. But the claim is intriguing. As far as I can see in the article there is no mention of evidence regarding a class differential in marriage rates, although it is well known that the rate is in downward trend. Food for thought here. Why might those from lower social classes be less inclined to marry? Money? Culture? Both? Discuss.
