The dream of most ordinary people is to own their own home. When prices are pushed out of the range of ordinary people then the citizens have just sold their home overseas and can only rent it back. That can't lead anywhere good.
It's the end game of greed in which we have sold everything including our homes.
Countries no longer need to invade other countries - they just buy everything. It's a strange thing that there is an obsession with the risk of terrorism but selling real estate to other countries is not seen as a threat to national security.
If the government cared about its citizens then selling residential real estate to non-citizens/permanent residents would be outlawed. But instead what we get is a clear illustration that in our society the only thing that matters is money - our country is no governed for the people, its governed for the dollar.
The disaster can't be undone because governments will see the flood of cash and tax it, becoming addicted to the revenue and if anything, try to make more of it happen.
This will end badly one day, when ordinary people realise that the rich sold their dreams and ambitions to other countries.
