Do you understand the concept of inflation, The currency we use to buy houses goes down in value by atleast 3% per year, So to think property would not go up over time in $$$ terms is a bit crazy.
Add to that population growth, there is population growth in Australias capital cities, this increasing density will also have some effect of pushing up values.
No, never heard of inflation.
You ever heard of nominal inflation ?
House prices should at beast increase by inflation, not four or five times inflation, which leads to a real price increase. Ever increasing house prices are ridiculous and we're seeing the result of decades of ridiculousness right now.
If I earn $100 an a can of coke costs $1 then in 5 years time if I multiply both numbers by 5 it is still the same percentage of my income.
If a can of coke all of a sudden cost 15% of my income, rather than 1% would you call that "progress" or a backwards step, because the average worker can no longer afford a basic item like a can of coke.
Or ... all those coke investors... making society better my making coke cost $500 a can.
