I'd recommend the reading that others suggested. And the fact that nationwide we are looking at 30% c-section rates, over 50% induced or augmented labors, and terrible morbidity and mortality rates for hospital births. Statistically home birth is as safe or safer for low-risk women, and some that are thought of as high-risk as well. One of the factors contributing to those stat's is the prevalence of unneeded interventions. Continuos EFM has only been shown to raise c-section rates, not improve outcomes. Pitocin causes fetal distress, and blood pressure issues for mom, but is still handed out like candy. Epiduals have many risks and force you to labor in a counter-produtive posisition. Multiple VE's increase the risk of infection yet tell you nothing, but they are still routine. AROM risks cord prolapse, infection, and increased risk of fetal distress, but is still done routinely. Cyotec is still being used to induce labor, even though it can cause uterine rupture, and is not approved for that use. Then you have the hospital policies that are based on nothing more than turn over. If your water is broken x hours you must have a c-section, or pit. If you don't dilate 1 cm an hour (or 2) you have "failure to progress" and must consent to x intervention. Which failing that standard means nothing, just that you don't fit their definition of normal. Policies against vbac even though evidence shows that it is safer for most mothers and babies. Routine c-sections for twins, breech, and in some places just posterior presentation. Then the number of times invasive procedures are done without the womans concent and even after refusing it. Birth rape a trauma are not infrequent at all, and all cause emotional damage, some very serious physical damage. I know a woman who while shouting no, had a Dr. pull out her uterus while trying to manually remove the placenta, there was no reason for that to be done it was moments after birth, and she was not hemmorraging. I'm realizing that I have left a lot off this list, but this at least gives you an idea of some of the things we are trying to avoid. I know at home there are some risks, but knowing the risks that the hospital carrys I am happy to choose homebirth.
Then on top of all of that is the emotional side, some people can relax and have a good hospital birth, I can't. It panics me and makes labor much more exhausting and painful. I also don't think that pregnancy and birth are an illness, there is no way I would go to the hospital if I wasn't sick. So now I give birth at home. Maybe that helps? I'm glad you were pleased with your experience, but I see the opposite way. When homebirth is such a good option why would anyone go to the hospital?

ETA: I know all these things don't happen to everyone who chooses to birth in a hospital, but the fact that they occur so frequently should give anyone pause.
