It would be wonderful if one could say all beekeepers care deeply about their bees and would do anything to keep them healthy.
People keep bees for different reasons and have vastly different amounts of time to spend with their bees. I have great respect for the people who are thinking about getting into beekeeping and then conclude that they don't have the time to do right by the bees.
As I have said before location is huge - both as a determinant of any local bee population and the environment that the bees live in.
In my area, truly local bees are hard to find as numerous colonies (I'm guessing between 35-40,000 into my County) are imported for pollination each spring. Those imported bees overwhelm the DCAs, potentially diluting any attempts at breeding I might make. [There is a drop of 100+ hives down the road about 4 miles from my home.]
In other areas local bee populations interbreed with Africanized bees. Are those resultant bees better able to coexist with mites? Ah, my answer would be yes. Are those bees unmanageable? I say "No." do the TF Bees I'm keeping now have some African lineage? It wouldn't surprise me.
Understanding what is going on in the hive is crucial. Depending on your available time to learn about bees, you could easily blame a hive lost in winter to being stuck where there were no stores when a cold snap hit. But if you've got time and knowledge you start asking more questions: Why was the cluster so small that it got stuck in an area where there were no stores? The search for answers is ongoing, someone will always be there to say "you didn't take this into account."
HITS is recognizing that mites are a terrible problem for bees and pretty much unless you do something about them (that is consistent with your philosophy) your bees will probably die. It is not saying that mites are the end of the learning curve. Obviously there are many factors that contribute to an area being either a good or a challenging place to keep bees. It is simply saying that mites can't be ignored.
I'm delighted that there are beekeepers like Kirk Webster who go about their business keeping bees and continually learning about them. I don't have unlimited time to devote to my bees - they are a hobby for me and I have other interests. The prudent course for me is to 1) keep an open mind and 2) to somehow absorb some of the vast information on bees and beekeeping that is coming out.
In the end all I hope to do is keep my bees as healthy as I am able to, using the resources at my disposal including whatever human intellect I may possess.
