The stock market is endlessly talked about in financial news, but it means very little for how well most Americans are doing.
Ryan Cooper, in The Week:
…If we break the population into 10 groups (or deciles) based on how much stock they own, as Matt Bruenig does with the Survey of Consumer Finances of 2013, we find that the top decile accounts for 86.8 percent of all stocks. The next decile owns 9.5 percent, the third 2.8 percent, and the rest little or nothing.
In other words, the richest 10 percent of Americans own a giant super-majority of the stock market…

Stock markets, meanwhile, are supposed to "intermediate" between savers and borrowers — channeling investment to the best performing and most promising companies. But as Doug Henwood writes in his book Wall Street, it does not work like this at all. In reality, the stock market is a political-economic control mechanism. As Matt Stoller writes in his book Goliath, Wall Street raiders have continually pressured well-run corporations with low debt, high investment budgets, or high wages to cut costs and vomit forth profits for shareholders through dividends and share buybacks. Indeed, by buying a controlling share of stock with borrowed money, hostile takeover specialists can put the debt on the company's own books — thus effectively buying the company with its own assets and money.
Now, it wasn't always this way. In the post-Second World War generation, there were strong unions at most big corporations, which could protest or strike to defend their share of the corporate surplus. High top tax rates also made it less fruitful to try to grab down as much income as possible. But those days are long gone now. The fraction of GDP going to labor has fallen sharply since the 1980s, while the fraction going to corporate profits has increased sharply, and the share of income and wealth taken up by the very rich has skyrocketed.
This brings us to the deeper problem with an economy geared above all to goose stock prices. The broader economy, including all these public corporations, is still based on mass production and consumption. It follows that as inequality grows, the economy will sag and slow, because rich people disproportionately save their income rather than spend it, usually by buying financial assets like stocks. So as the financial markets are swamped by a tidal wave of profits, those stocks in turn become ever-more divorced from the health of the underlying corporate enterprise. The result is a marked tendency towards financial bubbles, as oceans of money slosh here and there looking for safe returns that can't exist because the mass public has little disposable income which would justify fresh investment in real enterprises.

The stock market is surging under Trump largely because of the massive tax cuts for corporations and the rich that Republicans passed in 2017. Contrary to their promises, corporations spent most of the windfall not on investment, but on dividends and share buybacks which fueled gains in the market. Wages, meanwhile, are up slightly, but not anywhere nearly as much as stocks. Overall growth is also weak. This means the stock boom is built on sand…
