Large for-profit corporations are never going to be that interested in providing anything other than a relatively small range of products and services, because that's the most profitable approach. If everyone drinks Coke, you can build a Coke factory, develop economies of scale, and make large profits. If everyone has their own unique beverage with no preservatives that has a short shelf life, this doesn't scale, as now you need hundreds of separate production lines for each unique beverage. This also creates a desire for a homogenous population that can be easily marketed to, and ideally a rather dumbed-down population that can be herded like cats by AI recommendation algorithms into the appropriate boxes where their buying habits can be essentially dictated to them (along with their political opinions, ahem). Meet the brainwashed zombies of mass consumption... You really have to deliberately choose to not participate in this, but if you turn your back on it, you can still find lots of interesting niches outside of the Amazon-Netflix-Spotify zone - but nobody's getting rich out on the fringes, because margins are thin and there's no economies of scale to exploit.
