The good old days before petro-chemicals

I am confused as to what exactly the Multiple Chemical Sensitivity disorder "sufferers" want exactly. They seem to decry the modern use of chemicals as heinous, but these are the best of times. Remember the good old days when we used lead based paints? When we had lead in our canned foods? When our canned fruit and juice tasted like the cans? When one orange was an extra special treat? When malaria was endemic to the southern US? Before DDT, when we had lice, fleas and bedbugs in our beds? When open sewage ran into lakes and rivers? When we drank polluted water? When the smell of the family bedpan disturbed every one's sleep? When we contracted bubonic plague and smallpox and polio and typhoid and tuberculosis? When vermin ran over us at night? When there were no antibiotics and even President's sons died from blisters and rich people's sons died from ear infections? When people rarely bathed? When doctors bled people and dosed them with deadly poisons like arsenic and mercury to cure venereal and other diseases, which our husbands often contracted from prostitutes and gave to us? When we burned coal as fuel for heat and cooking? When we had to boil meat because it was spoiled? When rural people burned their trash? When factories belched out toxic fumes? When entire families bathed in the same dirty bath water? When women died in childbirth? When the infant mortality rate was high? When our life expectancy was short? Before blood pressure medication? Before ambulances could speed you to the emergency room? When the doctor had to ride for miles in the snow to get to you? When the cure for a cavity was to pull out your tooth, before you died from abscess? Before refrigeration? Before pasteurization(Odwalla juice anyone)? When farmers used untreated animal waste as fertilizer? When pests could wipe out entire crops? When were these marvelous, chemical free, good old days? I don't remember them.
