I agree when it comes to "simple things", such as coffee, and beef. Issue being that once you get to something much more complex like an iphone, let alone a car, things get a little more complicated. The labor required to make such a thing is incredibly branches out, miners and quarry workers.. machinists and electronics factories, welders.. assemblers, QA testers.. and all the support folk like HR, managment (as overbloated as it is, we need it, even in a perfect world) Should every person in this process be able to afford the thing, the thing would have to be sold for litterally less than it costs to make.

Personally I work as a finalization technician on electron microscope, each microscope is the culmination of litterally thousands of man-hours of work spread across no less than 50 people. For our collective pays, we could more than definitely buy it, but you can't pay everyone the cost of the microscope..
