french language

Two years ago I began learning Latin when I spied a grammar book on sale for 50p at my local train station (they do a recycling thing where second-hand books are sold for a small fee and the money goes to charity).
On all my travels I note that children globally can speak up to four languages as their norm. Why are the UK's youth the worst at wanting to and being able to speak not only good English, but any other language?
