I guess the deep trend for stock prices is tracking the median wage.
I don't think so. Stock prices tend to baseline on the value of the company, or discounted future value (time value of money). In the early 20th, value was primarily determined by dividends paid out, as company financial data was essentially never published. If the company could pay and grow dividends, it was doing well.... Obviously other factors also influence stock prices, both in the short and the longer term, see below.
As for wages, if the company is doing well -- selling more products, making more money, possibly hiring more people -- people become more valuable to the company and they get more pay. Otherwise they go find another company that will give them more pay. More pay, they buy more products. The economy does better. Etc. (Henry Ford understood this very well, as well as understanding the importance of pricing to reach customers -- the elasticity of the supply/demand curve.)
(Interesting side-note... you know why companies started providing other benefits beyond just straight pay? The benefits which could have been purchased using increased pay were initially added by companies to increase compensation because of labor laws limiting pay and/or tax laws taxing pay -- "freebies" were of greater value to the individual, or cost the company less than they would cost the individual. So in spite of the increased complexity, providing the benefit was a better deal than simply increasing pay. Unintended consequences... So gov't changed the tax laws to tax more benefits. Etc.)
People talk about demographics of people of investing age governing stock price trends
I do think there is a demographic trend -- increasing investors or decreasing investors will cause increase/decrease in demand which will correlate somewhat with increasing and decreasing stock price, respectively. The other factor affected will be the price/earnings ratio -- more investors, more demand, bid up stock prices, increase the PE and the converse also. Simple company growth in profits will not increase the PE, it might even decrease it but will eventually increase the stock price as the investors realize the increased earnings make the company more valuable.
In short, if you see changes in the PE it is due to price changing faster than earnings, or earnings changing faster than price. If it is due to price changes, you know it is investor demand -- either because of change in the number of investors overall, or because of a change in sentiment for this particular stock (or whatever your PE is measuring, e.g. an index or even a fund).
but deep down it takes a customer base able to pay for the products the companies sell. The developed world has had no real inflation adjusted increases in median wage for 30 years and so increases in stock prices since then look perilously like reversable froth. That period 100 years ago had an emerging class of consumers who provided the customers supporting stock prices. Do we now have little scope for increasing prosperity in the developed world? Are emerging market consumers the new hope?
It definitely takes a customer base, and growth requires increased consumption either from a customer base that is increasing in size or that is increasing in consumption per capita. (Obviously you can grow profits by cutting costs per unit, that has always ended even before growing consumption.)
I do think future growth will hinge largely on the emerging markets for both sheer number of consumers and consumption per capita. The U.S. (and to a lesser extent most of the developed world) has fueled consumption with debt. Our consumption was bound to drop, or at the very least slow down in its rate of growth.
On the other hand, as a dividend investor growth is nice but it is a secondary concern. If I have a goose that lays 4 golden eggs per week I do not fret about how to make my goose lay 5 eggs per week, then 6 eggs, etc. (I also do not eat the goose for Christmas dinner!) Instead, to supplement my egg production, I look to acquire another goose, or maybe a more affordable duck or a hen or even some quail.
To pay for the addition to my flock, I cut my consumption -- instead of consuming all 4 eggs per week, I might cut to 3.5, or 3 or even less. Once I accumulate the necessary capital then I acquire another bird and then I can safely increase my consumption. Or maybe I use the added production from my new quail to increase the rate I accumulate capital in order to acquire the duck or the goose I really wanted.
It's quite a different model than debt consumption... And without easy money from nothing who would loan me money solely to increase my consumption? Nobody with a brain! Yet that is what has been happening ("consumer debt").
Of course, I could probably find a lender if I were to create a business plan specifying how the loan will increase my ability to pay back the loan -- I know where today I can buy a goose that lays 4 eggs per week just like my existing goose. In return for lending me 60 eggs to buy the goose, you, the lender, will get 2 eggs per week for two years (or sooner if I can). If the goose dies, I will keep making payments using my existing goose, and if the goose lives I get an increase in lifestyle immediately, plus likely even better after I finish paying back the loan.
