While Deputy Prime Minister Barnaby Joyce's peculiar economic and fiscal views pose a threat to foreign investment, jobs and growth, yesterday there was a small example of his impact on issues that get less public attention.

Yesterday Joyce, who as Agriculture Minister holds responsibility for water, jointly released a consultation paper on imposing a "national register of foreign ownership of water access entitlements" with Treasurer Scott Morrison, a man who seems unable to tell the difference between a car and a house, let alone provide economically rational pushback against agrarian socialist idiocy.
