the US could turn into japan.
their Nikkei has been horrible for the past ~30yrs
Japan is the result of wealth accumulation gone wild + politicians that don't understand simple economic concepts.
In general, wealth accumulation can be a very good thing. It encourages hard / efficient work, because that may lead you to a better life than someone who works less hard or less efficiently. But, when taken too far, there are serious consequences.
In Japan's case, wealth has accumulated in the elderly, and for Japan the elderly are quite old. That means a typical 90 year old has a big pile of wealth there. I don't know much about the elderly Japanese myself, but having been in Japan a few times, the products on the shelf certainly do not appear to be geared towards the elderly. They seem to be geared towards the young who in Japan are quite indebted and often have no way to get a good income.
That means, the Japanese wealth is stagnant. Eventually, they die and the next round of 70-year olds inherit the wealth. Again, to another person who isn't typically a big spender.
What Japan needs more than anything is to encourage the spending of that wealth to get their economy back on track. So what does Abe do? Massive tax on spending. Sorry, but taxing spending is NOT how you encourage spending. He hoped to encourage spending by threatening even higher sales taxes in the future. Instead, Abe needs to do the opposite: threaten to tax stagnant wealth while cutting sales taxes. THAT will finally get Japan back on track.
Will the US reach that point? Maybe. Inequality here is building and building. But we are far from the Japan's place of zombie businesses and little spending.
