The big 4 Australian banks (Commonwealth Bank, ANZ, National Australia Bank and Westpac) all employ pretty much the same number of people now as they did 25 years ago, but their workforce composition has changed. More software developers, fewer branch staff.
I really hate the (very australian) propensity to take an argument about X, and make it about X as a proportion of Y, pretending they are exactly the same statistic.
LNP: Taxes less.
Labor: Taxes less (as a proportion of GDP)
(Seeing as GDP includes government spending, it seems like you can make the rate of tax go down by increasing government spending by more than taxes increase)
If a claim is about X, introducing another variable doesn't invalidate the claim about X.
In this case my original post that everyone was responding to here was talking about employment as a function of population as obviously a larger population needs more food etc.
Ignoring that when the global population is likely to peak soon due to falling birth rates is a massive mistake. Jobs in a world of falling population and increasing automation is largely uncharted territory.
