And everything has a price.
A land development near me was stopped because it had "cultural heritage" and had to be preserved.
Surprisingly, or not, a "confidential agreement" was reached, and the land got bulldozed. It also happened at another location in the Hunter Valley, and these precious bits of culture carried a price and have now disappeared.
As for the "Invasion Day", where would they be if we hadn't "invaded"? The previous 50,000 years weren't all that productive.
