Even today, when it is raining, my thermostat is set on 79 degrees, the optional humidity feature is turned off, and the relative humidity in my house is a comfortable 43 percent. It seems to me that if you need to set your humidity setting to 55 or 60 percent, you must be leaving a door or window open, or you are adding outside air into your house. The relative humidity in my house never gets that high.

OK I'm not challenging what you are saying but let's take a look at this. So, it's raining which means it's 100% humidity outside. But, in your home it's 43% and you have the temperature set at 79 degrees!
This can only mean a couple of things. 1) you have a very tightly sealed home or 2) your A/C is undersized and it's running a lot. You didn't mention a dehumidifier so I'm assuming you don't have one.
That said, you may have told us before but what type of home do you have? Block or Frame?
How many sq ft and what is the tonnage on your outside condenser? How many people living in the home?
Your home should have some natural but very small air flow between the inside and outside air. But your home might be very tight. Did you ever turn off your A/C and checked to see if the humidity rises? 43% seems unusually low for the summer months when it's very humid outside.
You are correct the A/C will only lower the humidity and can't increase it so when we talk about "setting the humidity" we are referencing how much the A/C can lower it while maintaining the set temperature.
