If they can invest in gold bars, why can’t they invest in Australian housing? Why choose & pick what they can & can’t, what you like & what you dislike?

People can invest in what they like, but why should central banks and governments skew the field so that people are pushed into certain investments en masse?
It's not me 'picking and choosing' at all. I am saying that the balance between saving and borrowing has been recklessly and deliberately destroyed. Savers are now punished, and borrowers are subsidised and passively bailed-out by the central banks & by taxpayers. The savers are subsiding the excessive borrowers. The savers have taken a massive haircut on their returns, and this is passed on the borrowers in the form of dirt cheap interest rates.
