It is complex but antibacterial soaps do make the problem worse.
The first line of defense your body has against foreign bacteria is not your immune system it is your own bacteria. When you wipe out them you create vulnerabilities in the system. Most antibiotic strains of bacteria don't survive very well compared to the non-antibiotic strains if no antibiotics are present. The same is true for many other resistance.
What this means is don't take things to an extreme. After you go to the bathroom you should wash your hands and if you get a cut you should clean it and seal it. However the constant usage of stuff like purell and putting it all over you in a bad idea. It also means that you should not take antibiotics unless you actually need them since they do wipe out a lot of your necessary bacteria also and can upset the balance of bacterial species within you. Basically we keep all those bacteria in check by making sure they are all in controlled numbers and use the balance between each of them to keep them in check. Your body is actually pretty darn good at this and even if you upset the system it will still usually repair it just fine.
In the end the message is don't take this stuff to extremes.
