Quote from Cutten:
Savings which are invested profitably also create value. You put in x and get back more than x. Again, you would not save if you did not expect it to create value for you.
I beg to differ - I don't think that's the way the world actually works. People ought to be rational optimizing agents, sweating over their mental abacus about how much to save and how much to spend, but I think the reality is that they make haphazard decisions all the time in this regard.
I think govt policies are a far more significant determinant in a nation's savings rate.
For instance, IMHO, the biggest reason why the US has an infintesimal savings rate is because of the pay-as-you-go social security scheme.
Consider this :
In the US, a worker gives a portion of his salary to the Govt in the form of SS tax, which then passes it directly on to the retiree, who then promptly spends almost all of it. There is no savings component in this scheme. Unsurprisingly, the savings rate in the US is negligible.
In Singapore, a worker gives a portion of his salary to the Govt, which then puts it into a fund. The funds add to a pool of savings. When the worker becomes a retiree, he can withdraw those fund. That's why the savings rate in Singapore is a remarkable 50%.
Although the $ flows in the two systems could be identical, in the first, $ goes straight from one pocket to another. In the second, $ spends 30 years swimming around in the capital markets between pockets.
It's true, the retiree could be using his SS checks to trade the ES

, but it would only be some small % of his checks redeployed in the capital markets. Given the cost of medical care in this country today, somehow I suspect this to be a small %. In the case of Singapore, 100% of the checks are forced to spend a spell in capital markets purgatory.
In Singapore, savings lower the cost of investment, which allow for continuing capital formation, the foundation for growth.
In the US, vendor financing lowers the cost of investment.
Remember when Cisco would sell routers to CLECs and then offer them loans to pay for them? Well replace Cisco with Japan + China and replace CLECs with the US.
