I don't wish for trouble at all. I wish people were better financially educated during their school years.
If the masses cannot be educated to a suitable level, then I wish the govt could enforce lending ratios on banks to keep property prices at around 6-7 times average single persons earnings. This would mean no housing problems or rental paying problems and the extra savings being put into other sectors of the economy and better investments. You property wannabe moguls keep whining about how bad the costs are so should also be on board with this.
With the bulk of my investments in health and copper I fear a general mining downturn myself very little. There's that financial education thing once again.
