Following in the footsteps of Functionalists like Davis and
Moore (1945), some people argue that without a small group of
super-rich folks at the top of society no one will be around to be
the first adopters of new technology, like expensive electric cars
that are good for the environment (think Telsa Motors) or the big
brick cell phones of the 1980s that cost a fortune. By purchasing
these early, very expensive technologies the rich pave the way for
later, much cheaper technology that the rest of us can afford, they
argue.
How might a Conflict theorist respond to this argument?
Which side of this argument (conflict or functionalist) do you
think makes the most sense and why?
