What are the costs?
Quite apart from the inhumane nature of evaluating the existence of one's fellow citizens in terms better suited to industrial cost-benefit analyses, this view of disability fails even under its own terms because it doesn't take into account that there's an awful lot of costs, burdens, and emotional devastation on the other side of the equation. I'll list just a few of them for my readers to ponder:
What does widespread discrimination against qualified workers with disabilities cost our economy?
When children are inadequately educated in special needs classes, what is the cost of the resulting loss of productivity over a lifetime of unemployment or underemployment?
How much emotional devastation do families suffer because of stigma, stereotypes, and mass hysteria?
What is the amount of money wasted each year on researching potential cures that are unlikely to result in anything useful?
When large numbers of people feel that they cannot get reasonable opportunities in our society and console themselves with drugs and alcohol, what is the cost of that?
How much potential for lifetime achievement is lost every time an autistic teenager commits suicide because of prejudice and social rejection, and how much devastation must his family endure because of his loss?
What is the cost of being expected to do anything it takes, no matter how difficult, expensive, or emotionally distressing, to fit into our society's extremely narrow definition of normality?
When public welfare agencies see their role as providing only the least possible assistance, rather than providing the services needed to enable their clients to find productive niches in society, how much more does that end up costing in the long term?
How many families spend large amounts of their savings, or go into debt, buying purported cures and therapies that are either useless or actually harmful to their child?
