I believe people are just better educated now, more critical of the media, and are more aware of the far reaching effects of the economy. The supermarkets squeeze suppliers, the suppliers go out of business, this reduces available jobs, money isn't coming into the communities, everyone suffers.
I'd like to think this is a mass movement but I suspect very few people will shop around to buy more ethically sourced milk. People will say that when money is tight they can't find the few extra pennies when in reality - just don't buy that bag of donuts and get the free range rather than factory farmed chicken! I've found shopping spend goes down when you're more aware of what you're buying.
I do care that we have lost sight of the importance of manufacturing and production in this country. We poured investment into "service jobs" - nice clean call centre jobs - only to see them disappear to cheaper labour markets within 10 years. Once a manufacturing business goes out of business or relocates abroad, it ain't going to come back. And neither are the quality careers and opportunities for our young people.
As consumers, if we shop more wisely, we can make an impact on this. (Of course we can vote, but the politicians are more or less in the pockets of the corporates and need the donations). Shop local, shop independent, know where and how your purchases were made.
