elderly will not require Japan to open the immigration gates to foreigners. And because machines don't need health care it will also mean that the cost is vastly lower than funding humans to do the same job. You can't solve big problems by separating them out and trying to solve them on their own. You have to come up with seriously big ideas that in their execution solve multiple problems -- or at least have the potential to do so. What we need to do is to create a resources tax that is directly linked to investment into new technology that adds value in the resources sector. The idea should be like the 10BA tax deduction was for the film industry years ago.... Tax the mining companies and then give them the opportunity to get a 115% deduction from investments in innovation that value adds to the raw materials that they mine. So instead of for instance shipping zinc ore to China or Korea for it to be processed, build plant and equipment near the mine head where the zinc can be processed here -- and then sent to China or Korea to be put into products... Repeat that across a host of mineral mining projects and soon we will have a real solar energy business, because the materials that are used predominantly come out of mines in Australia. Maybe even have various levels of tax deduction based on how much innovation risk is involved... This should not be rocket
