You've drunk the neoliberal cool-aid so deeply you don't realize the definitions you use for words have been hijacked. Investing is not necessarily a finance term, there are a lot of investments societies make that don't return a direct profit -- in fact I'd say the vast majority of investments societies make don't "return a profit" in the mentally-challenged definition you are using.
If we had followed the neoliberal definitions you rely on during the earlier eras of the nation we would've never built roads, let alone the massive infrastructure that allows our society to function so efficiently. Roads, schools, waterworks, electrical utilities, telephone networks, the internet, hospitals, shipping terminals, passenger rail, semiconductors, the space program, the sciences generally... the list of what we wouldn't have if we lived and died based on the definitions and ideology you espouse in that one sentence is far greater than the list of what we would have. It reminds me of the libertarian fools who completely ignore all of what it took to build the physical and intellectual commons we all rely on so they can demand we put an end to all that foolish public investment. We'd all still be living on feudal estates (most of us would never have been born of course) if your mindset ruled the past two centuries. Amazingly, shockingly ignorant comment, yet par for the course in todays shockingly selfish and shortsighted neoliberal stupidfest.
P.S. And I'd like to add that its this same ahistorical, sociopathic denial of the public good, the commons, that is responsible for the constant degradation of our national infrastructure: a fragile and failing electrical grid, roads, public utilities, state infrastructure, the vast public education system all deteriorating at accelerating pace; no buildout of the infrastructure that will make us successful in the 21st century and beyond, and no addressing the clear and present facts of capitalism's failure to provide for the needs of the people and society. After all, the capitalists sell capitalism as the system best able to provide the most happiness. Or at least they pretended that when they had to answer the criticisms of the communists. Now the story is everywhere yet somehow unstated, but goes something like "to the victors go the spoils", which is as anti-commons as one can imagine and sociopathically ignores the existential public acts that made the spoils possible in the first place. That whole "I made this"/"you didn't make this" silliness only served to obfuscate the obvious, undeniable fact that we are nothing without the communities we are part of. Without them we'd have an almost impossible task everyday, like living out on the prairie in 1830: doing everything for oneself. The neoliberal pretensions of self-creation and individuality only avoid shocking us because they're so common. The "great man theory" of journalistic and historical analysis are commonplaces in our media from Hollywood to (lesser) historians to the everyday claims of self-righteous business douches, and yet it is utter horseshit. Even the great "wiz" behind Apple, Steve Jobs, was technically weak and relied on his less photogenic partner Steve Wozniak for the technical knowhow.
The insufficiency of what is termed "free market capitalism" but is really oligopolistic, rentier-dominated lemon socialism is everywhere apparent. The denial of the commons, indeed of our common humanity, flowing in a constant shit stream from the power-elite and their ocean of lackeys and buttlicks shocks the conscience. Neoliberalism is at heart denial of conscience. It preaches the "disutility" of the conscience. Neoliberalism is the cruelest of the capitalisms as it preaches that selfishness is the truest morality, totally eviscerating the need to feel for one's fellow human. No longer must we dehumanize our underling in order to abuse him. The primary neoliberal "moral" principle is denial of mutual human obligation and thus in one move attempts to turn morality into its opposite.
