Things are getting built for the 1% because they have the economic power, but I'd imagine OP thinks this is undemocratic (which it is) and results in many people becoming underserved by software companies (very likely).
What is getting built for specifically the 1% (or .1%, etc.)? The only service I can think of is Magic.
Additionally, what markets are underserved? This is an area I'm interested in but don't know much about (except from my own anecdotal experience like the fact that comparing costs of healthcare from different practitioners being prohibitively difficult)
Should clarify that by "specifically for" I'd mean that the 1% have all the money and thus practically all the decision making power. An example of the distinction would be that though everybody engages with AdTech software the software is built for the 1% to make them money.
The 1% isn't a demographic that's targeted by some SaaS in this case, it's a way of naming the rich who create the demand for a lot of software (they use the software to make money) and control the (high-level) implementation of most software in the world.
Not OP, but I think the point here is that very few end users have a say in the tools they use. You sell the big company on your software, one or a few elites like it, and they buy thousands of licenses for all of their employees.
