I dunno man my wife takes care of our one-year-old not just staying at home but going to the library and stores and the nearby petting zoo and stuff, and he's only been sick once, after a long day of air travel where my wife and I got sick as well—whereas, friends' daycare'd kids are sick all the time, constantly having runny noses and such. Just something I've noticed, is all.

Outside of society being oriented around having my wife work and sending our son to daycare rather than having her raise him at home, everything's going great so far, one year in.
