If optometrists ran the country, they would be asking us if what they showed us was better, worse or about the same before they gave it to us.
If optometrists ran the country, their goal would be for us to see it clearer and they would be doing all they could to accomplish that.
If optometrists ran the country, they would want us try on what we were going to end up with, and to be happy with what we finally ended up with.
If optometrists ran the country, they wouldn't try to give everything away. They would realize, that someone was going to have to pay for what we got.
Of course, if they were evil optometrists, they would convince us that they knew best and that the world was supposed to look fuzzy and that seeing the world clearly would cause us to go blind.
