ELI5: Why are migrants willing to pay thousands of pounds to get from France to Britain when France is a pretty nice anyway?

There has been a lot on the news about how migrants are swarming Calais to get across the channel and are paying thousands, or even tens of thousands of pounds to be smuggled over. What is so attractive about living in Britain instead of France?

The bottom line is, the UK spends a lot on welfare for domestic and asylum seekers, and the welfare is more easily accessible compared to other European countries. Also, French welfare benefits have more stringent criteria, and stop after a certain duration. Furthermore, countries like France, Sweden and Germany crack down on illegal immigrants more so than the UK, and although they take their fair share of immigrants, they are more inclined to decline asylum.

Migrants get told stories about how great it is to live in the UK regarding opportunities. They pay thousands for travel and to be smuggled out their country etc. just to get here, and usually end up in massive debt. 

At the end of the day. They want a new life, to escape persecution, to be able to live a life they can be proud of, earn a decent living, and give their family a brighter future.  They are not stealing 'your jobs'. They have sacrificed a lot to get here, in the hope of a better life. Not necessarily always legitimately, but it is an admirable feat none the less.

Edit: clarity

For those of you who say immigration is bad. Get a god damn education on the topic before you start making arguments on what you don't understand. Immigration is the bedrock on which the greatest nations in the west have built upon. Granted it needs to be handled, and managed efficiently for sustainability and controlled growth in the 21st century. But it is vital none the less.
