Yep. it's been out of kilter for years, and, as said, those pandering to that model will squeal if their 'superiority' is threatened.
The forbears of one of my very good owners [ H.C Greenwood ] took the famous Gloaming from Christchurch to Sydney to have his first start in the AJC Chelmsford Stakes. That would have entailed a boat trip, no mean assignment for a novice galloper - but he duly obliged.
No doubt granddad had a punt too...but does anyone seriously think that such a herculean task would have been undertaken if the money and prestige had been here?
NZ-ers accepted, then, that the bigger population/economy enabled better money, and also the chance of a decent bet.
You have to question the intelligence - or veracity - of those who hollered recently about 'rising stakes'....however, no doubt they were able to purchase nice new yearlings on the basis of that......
