I think you're right, but not in that way.
Tesla charged wealthy people a lot for the original tesla roadster. Then they took what they learned and charged wealthy people a lot for a better car, the original model S. Then the X.
He continued reaching into the pockets of wealthy people for further updates to the model S/X, updating the motor, then motors.
Now the model 3 and Y are available for less wealthy people. I'm sure the next generation of tesla cars will be more affordable, maybe even Jimbob.
