Continual accelerated growth.
What I've never understood is where this eternal growth is supposed to come from... Sure, in the 60s, there was a boom in the productive workforce and thus disposable income in society, so increased revenue was almost a given.
But in an age where there are fewer and fewer wealthy people entering the marketplace and with even fewer predicted in the future, how do companies expect to continue raking in the money?
Recent data from the US (and not to mention the UK, the only G7 economy to show actual direct decline) has indicated the largest drop in "relative disposable income" since the Great Depression almost a century ago.
We have seen tech companies' and the energy market's approaches: Increase the price of equivalent or lesser products and reduce availability.
Hence the fact that companies are ratcheting up the price brackets to compensate for losses in sales volumes even while raw costs are starting to fall. (Energy being basically non-elastic is especially egregious in this respect).
But that is eventually self defeating since it mearly redistributes finite expenditure elsewhere. Add this to the reality that even what actual money there is now more and more tends to be concentrated in fewer and fewer hands: the hands of the owners themselves rather than their customers'.
Thus at some hypothetical point in the future, there will likely be more money within the special club itself than outside and options for future growth will become increasingly sparse, if not entirely absent.
