On one side of the scale, the Nazis practiced euthanasia of severely handicapped and mentally challenged people whose lives were deemed “not worth living.” On the opposite side, the UN adopted idealistic conventions on the rights of people with disabilities.

The conventions ban employment discrimination against the disabled. That amounts to a hefty tax on employers who have to hire the disabled only theoretically suitable for jobs. Many handicapped people are otherwise healthy and decent, but many are not. Governments should not require private employers to run charities.

Affirmative action for the disabled creates a new class above the rest. Companies can rarely formulate the reasons for firing employees with mathematical precision; “underperformance” is a vague term open to claims of abuse.

Mentally disabled people pose a bigger problem. The convention requires equal housing opportunities for them, but many sane people detest having such neighbors. Pushing the duty of housing the mentally ill people on the public is wrong. Governments charge taxes and should provide hospices to visibly insane people.

Historically, life expectancy among disabled people is low. With various benefits and medical treatment, usually at public account, the percentage of disabled in the total population is rising. While the UN figure of 650 million disabled worldwide is grossly inflated, their number is huge and grows particularly as the population ages.

The only option to control the costs of servicing the disabled is to relegate them to private charities rather than private enterprises.
