Is population aging beginning to affect North American businesses?

I came across something I wasn't expecting to find in an article named Agriculture minister's all about buying local:

Chuck MacLean, chairman of the Alberta Beef Producers, pauses over Hayden's 50 per cent goal. People may be interested in supporting local farmers and ranchers, but North Americans are getting older, eating less and buying less food. Ranchers still need to make money, he says.

"The product needs to go where it makes the most amount of money," MacLean says, namely China, Japan and Russia."

If you had more population or people ate more, then you could keep (produce) at home," he says. In the meantime, he says, there needs to be concentrated effort on pushing exports offshore.
