You were probably better off as a programmer. I was working a UAT for a software implementation, and was working with a consultant, whose spouse is a well respected (#1 in her state) cardiologist (I believe)., and he said after taxes, insurances etc, he makes significantly more as a consultant than she does as a doctor.I have never heard of transdermal lead transfer. Out epithelial cells have semi-permeable membranes that block most everything. And I've done a lot of research on this subject 'cuz I don't wanna be stupid and sick, and have to take chelation therapy. Once upon a time I was going to be a doctor, but at the last second decided on a career in computer programming (a stupid decision I have always regretted).
Indeed, WebMD, who I trust, doesn't have "poverty" listed as a cause of lead poisoning. I suspect the site you listed is an activist site run for the specific reason of spreading misinformation for political goals.
What Is Lead Poisoning?
Lead is a metal that’s found in the earth. But it can also be poisonous to humans and cause serious health problems, especially in children.www.webmd.com
that said, everything you are stating about lead, coincides with what I’ve heard and read.
