A person who struggles to put food on the table and a roof over their heads, for one.
I just watched a video about how inept politicians caused a food crisis in Sri Lanka because they thought they knew better than scientists, chemists, and farmers: https://youtu.be/1S2wwbX_p_E
My parents made only a few luxury expenses: encyclopedias for us children, and especially books about space and the cosmos. So please speak for yourself when talking about the interests of struggling people.
But alas, after many years of convincing people that going to college makes you dumber, enough people have started believing it that they willing vote against their own self-interest.
Most of humanity shared this existence, and yet the language, institutions, ontologies, etc around existence come from those people who did not have the food and housing security of most Americans.
The counterexamples are numerous, but just start at the arts and you'll quickly see there is not a correlation between material comfort and basic curiosity.
Today's standards are yesterday's luxuries which were the day before's scientific breakthroughs.
And the idea that science is what's breaking the bank when it's barely a rounding error in the US budget is laughable. It's hard to get exact numbers for all R&D funding vs how much we spent on the Iran war but my estimates put just the single Iran war at anywhere from 20-50% and the goals for the Iran war are even more abstract and arguably make things much worse for average Americans on a day to day basis.
Indeed, not only did research programs get cut, but so did USDA funding which both balanced farming and put food on table. And this was a year after the previous administration reduced the deficit, sent food funding to states, of which ~13 rejected the funding.
Food funding, which, has been studied to increase economic output beyond it's costs, similar to research funding.
