In humid climates such as Virginia, mold can be a real problem in homes and other poorly-ventilated areas. There are lots of health issues associated with household mold, but fortunately, there are many ways provided to us by capitalism to fight mold. Dehumidifiers, both large and small, can prevent mold from forming. Should mold form, there are lots of products that make cleaning mold easy and cheap. So, for less than an hour’s worth of work for the average American laborer, s/he can clean their bathroom from mold and prevent it from growing again.
This is just another small example of how our world is becoming a cleaner and better place.
