That could be the case, particularly in cities where there is as big of an attraction to live in the city as there is in Manhattan, London and Paris. If income opportunities are high enough and lifestyle attractive enough to attract the skilled and well off, prices should match.
This is why I think Sydney, Melbourne and Brisbane have so much potential for further growth. They are very desirable cities. Sydney has been regularly regularly voted as the World's Best City...

Isn't it amazing that a city voted as the World's Best, still has much lower property prices than many other large cities in the world.
Sydney has extreme limitations on future physical outward expansion, being surrounded by ocean on one side, and national parks and mountains on the other. So the only way to install more accommodation is to move to higher density. But the existing residents make sure that happens extremely slowly. The result... very high demand for existing property.
On a micro level, take for example Sydney's Northern Beaches. Constrained by harbour and national parks on one side, and ocean on the other. There is simply nowhere to spread out to. And the residents won't let high rise engulf their leafy suburbs and block their nice ocean views without a fight. The result... only the investors or the rich can really afford to buy there. The people with the money... the people for whom wages growth is irrelevant.
Normal people are priced out so they fight for other suburbs as close to the desirable locations as possible. They push up prices in these areas. This spreads to all the suburbs. The city has no more room to expand and prices go through the roof. Those who can't afford it move to satellite cities or into the countryside.
In the future as more and more people work from home, living in satellite cities and the countryside won't be such a big deal. Commuting will become less of an issue.
But those who can afford, the rich, the investors, will still want to buy in the city, where the action is, near the beach etc. And the prices here will just keep going up.
