To reiterate my last statement, Really? Are you absolutely sure about that?
Are you sure we are getting richer because we are producing more, and outcompeting everyone else? Are you sure our riches aren't being entirely nullified by our increasing debt that everyone will have to either pay back or let the country go bankrupt? Are you sure people's net worth is just = bank & stock savings, and not = bank & stock savings - personal debt - national debt?
Are you sure our current system is even sustainable? I'm not, though I am very sure that Greek and Icelandic citizens thought theirs was.
I've had a good day farming gold so the "getting richer" part was personal. Maybe it should be left out.
My impression is that most people with jobs are happy as their mortgages are low due to low interest rates and inflation is low.
As you and I discussed in another thread, there is a sustainability problem that a large percentage of our populations are doomed to unemployment. I meet one guy every day and as he gets closer and closer to having to sell his home, I can see its killing him. Countries in the developing world sustain unemployment rates of 40% or so for decades and we have a long way to go before things get that bad.
I don't believe national debt is a problem. Its generally owed to pensioners and it amounts to a tax on savings since most big countries now borrow for less than the inflation rate. If the whole thing goes wrong, well, how bad is it that the have a few million angry grannies? Iceland is doing fine and it defaulted in 2008. Same for Argentina.
So on balance, yes, I'm sure its sustainable. There is nothing out there that worries me in economic terms.
