Marketinfo claims Sydney and Melbourne are "Glorified Refugee Camps'. To add insult to injury, Mraketinfo claims that "Hybrid Vigour is a racist comment as it implies superiority to the two genetic groups that it has sourced its material from."
The facts are: Merino sheep ARE superior to the African, Spanish and English sheep that John and Elizabeth Macarthur mated to get Hybrid Vigour to withstand harsh Aussie conditions and produce wool that sold at a premium to three genetic sources.
Britannia ruled the waves and conquered an Empire due to the inter-breeding of Saxon, Norman (French), Germanic and other invading or conquered breeds that gave Hybrid Vigour to the British Empire until Singapore fell in WW2 when a new Hybrid nation emerged: America that still rules the waves but has China catching up fast.
I worked in the CSIRO for two years. Hybrid crops, sheep and cattle ARE superor to monocultural breeds.
Sadly for racists, white people are not a superior breed of cat.
