HN kicks up an almighty fuss about any attempts to regulate our industry (see online payments, sales taxes, etc.) but we are happy to pass judgement on others. In Europe we can barely stop people from selling horsemeat as beef. I'm not sure how effectively we are implementing any of these rules, and I'm sure a farmer who wishes to do so can flout them at will. One positive thing to come from the rise of supermarkets…
In every industry, the people within the industry think that "they're different" and because they're morally upstanding they don't need to be regulated, but all those other fuckers, well they need to be kept in line. On HN you see this very clearly with attitudes towards the tech sector versus the financial sector (meanwhile my non-tech friends wonder why Facebook and Google are allowed to basically stalk you through the internet).
