Money supply growth, massive immigration, how are they connected and what happens when ms collapses?

I was struck by Chris Martenson's comment that growth of population is necessary for growth of money supply which has to be for the economy to stay in the same place.

In the light of current brouhaha in the UK over Nick Griffin's appearance on BBC's Question Time, and the anger over the BBC's schoolyard bullying of him combined with the basic fear of massive immigration over the past few years, and typical comments in the media that the very visible increase in immigration forced by the government whilst people who were born here are homeless, I did wonder what lies behind the way the government encourages millions of immigrants and furtively lies about it.  Do they need all these people to keep the money supply rising? 

What will happen to these immigration issues when the money supply collapses under its own absurdity?
