>You're wrong in your theory that accumulated wealth does nothing. In a QE world, the very rich don't sit on cash - that would mean losing money through currency decreases.
Correct, but they still don't spend money. The very wealthy are known to hoard money, it doesn't matter in which "vehicle" they store their money in.
>There is no such thing as 'wasted capital' - rich people store their wealth in a variety of vehicles - whether in banks (where it is re-lent out for many uses), public stock ( where it is used for company investment and operations), and private investment, such as investing in pre-IPOD start ups and private equity.
It's not wasted capital, but it doesn't stimulate the economy either. They are not contributing to investment, in the real economic sense.
>Even Apples massive cash hoard is put to good use, somewhere.
Wrong.
>It's a very cartoonish model to imagine a daddy warbucks with a big pile of cash saying 'I just don't have time to spend this'. In actual fact, there would be a team of investment managers saying 'we can't find any good places to invest, so we're letting the bank invest it for us, for the time being'.
It's still not real investment. I think you don't understand what the "I" component in GDP is. [0]

>The answer to Japan's problems is cutting government spending and debt. This has always been the answer, this will always be the answer, whether you're an individual with 20k in debt or a country with 200b in debt. The key is to realise that there is no magic Keynes multiplier.
Wrong again. Greece cut their government spending a lot, they don't seem to be in great shape. The reality of the matter (while counterintuitive) is that deficit spending helps stimulate the economy. As long as Japan wants to devalue their currency, government spending is the last option left to stimulate their economy.
