Ahhh, I see. What you mean is that both you and your kids are going to work, underpaid, in elderly care. Underpaid, because the cost of what you do will have to be extracted from the working population, which won't include the elderly, and obviously taxes over 50% ... well a proportion over 50% can't double. The elderly population will more than double though. So the pay for people working in elderly care will have to go down, yet more people will have to do it and they'll have to care for a more elderly per worker.

The problem is that there are very large consequences to anything but the smallest of population changes for those who remain.

Also: Global warming (or at least the co2 increase) WILL stop before 2100 for the simple reason we'll run out of oil. I mean peak oil, we can fight about when it will happen, but before 2100 economically viable oil will be gone in practically every scenario. So why bother?

So you want to kill the rest of us?
