It's why I've always been wary of this forced participation in the securities markets the US seems to have. It's forcing folks to gamble at a casino for the chance to retire or grow their earnings, using historical models to support arguments in lieu of actual regulations or guarantees of returns (like dividends, bonds, or interest rates on savings).
There's probably a broader participation in the market (re: few people) than most of history, both direct and indirect. That can be good and bad.
There's definitely a speculative component but it's nothing like a casino.
Maybe you get dividends, but you’d get more value from the comped room and buffet at the casino.
I hate that argument, because it's the equivalent of my saying I won a board game by preventing too many people from playing it with me, starting with most of the resources already in my possession, and changed the rules so it's harder to spend those resources than to acquire new ones.
As of 2022, Vanguard owned two-thirds of US companies by outstanding shares. That's one institutional investor controlling much of the marketplace. Literally everyone else - other institutional investors, retail investors, governments, corporate employees, etc - is competing for the scraps. If we're talking people, the top 10% of Americans own 93% of US equities according to a 2024 study - again, everyone else is competing for scraps.
So while you are technically correct in that stocks represent ownership, your detractors are more "spiritually" (as in, the spirit of the argument) correct in that it's an irrelevant point when the vast majority of US Equities are held by a fraction of the population. The argument falls apart completely when you consider Capital Gains are treated more favorably by taxation than wages, which is intentional.
So to John Q Public? It's a casino. They have zero hope of actually investing or having a say in corporate outcomes.
I'm not sure why the capital gains argument matters here. If the business can return money to shareholders in a way that increases their capital then they'll prefer to do so (e.g. via stock buybacks) but that benefits the fractional owner the same way it benefits the large owner.
It's true that if you own 0.0001% of a business you have very little influence about how it is run in the day to day. But the value of your investment is still anchored to the value of the business in exactly the same way as the larger owners are.
Also, companies don't exist in a vacuum. Every US company is impacted by the actions of the federal government. Some companies may be able to come out ahead, but many others will struggle. And predicting which is which is incredibly difficult.
There is no "should".
You have hundreds of millions of people predicting the future using different models and heuristics. The future is a moving Target which also depends on what people think about it.
A big factor of stock performance is the r market’s assessment of risk and its risk tolerance.
Both of those can change, and have nothing to do with company performance.
