I have a set of outlets that the top outlet is controlled by a light switch. They do not work. I get a reading of 79v at all the outlets and at the switch. The bottom outlets all work and read 120v. The breaker controls all of them.
Any suggestions

Check voltage from hot to ground,if 120 then look for a bad neutral
This is called a "split receptacle". The upper and lower portions are separated by the removal of a small metal tab between them on the "hot" side. The upper and lower share the neutral, that tab is intact. If you are getting 79 volts on both sides of the switch then check the connections on the feed to the switch. If one side is 120 then replace the switch.

The power is there but not to that one switch. Can wires go bad so that they do not deliver enough juice?
Though anything is possible, I would say that wires don't "go bad". What do go bad are connections. Check the connections. Determine where the wire carrying power to the switch comes from. There is a good chance the problem is there. You're dropping 40 volts somewhere, this should be attended to.
If you are measuring across the 2 wires at switch, with switch off, or wires disconnected, then you are reading voltage through overhead ceiling lights.
Are you measuring across switch, from ground, from neutral?
All these measurements should be to the neutral.
I'm just wondering if he is measuring across the switch when it is open?
