Dear Mr Duffy,
I enjoy your articles and agreed with all your points regarding real problems we face. I would have been happier to see you mention the demographic time bomb America faces from massive and totally unnecessary immigration. The only people in favor of massive immigration, benefit from it and pass on all the economic,social and environmental costs to the communities.
I think we will soon become a divided ethnic and tribal nation, unable to govern or agree on anything and become a weak nation ripe for the picking. Diversity does not make a nation stronger, Unity does.
