We can all agree to blame Jack Welch as shorthand though, I think.
There's also risk in investing in very long-term things that may not pan out.
WAI, in other words
The only major example I can think of is Amazon dot com which famously reinvested all its profits into itself for well over a decade.
The fact that investors didn't punish Amazon dot com was seen as befuddling in the press.
> Companies routinely lose money for years in pursuit of long term growth.
No, I don't think this is true at all because you used the word "routinely". I would claim it is very rare.
I mean, I agree that such companies are over-represented in thinking about small businesses if that's what you mean. Normal companies have to be profitable quickly for sure.
It feels like tons of companies get valued based on userbase or revenue or theoretical breakthrough rather than ever having to really think about breaking even, but I know that's just because those folks get all the press.
Some money is lost to push up this valuation or valuation based on some future sales, or market share or anything...
But much of that long term growth now is just the company growing to displace competitors in existing markets, often by subsidizing prices and dodging regulations - see: Uber, Lyft, Air BnB, etc.
We've all seen the playbook a dozen times now: move into a market, keep prices artificially low until the existing competitors are displaced, then the raise prices to return the initial investment and more. That kind of growth-by-displacement is genuinely necessary sometimes but in these cases it's more like a fungus than a plant, just metabolizing an existing system.
It's not the same thing as actually expanding a market or investing in concrete assets (steel mills, power plants, boats, railroads) or R&D that compounds future growth. When the actual investment is just spent artificially lowering prices there's no actual efficiency gains and the consumers ultimately pay the price and more when the company hits the peak of the existing market and shift to enshittification mode to really extract wealth.
