Hendrik #Streeck ,a leading politician in #Germany 's #CDU #government party (and #university professor of #medicine ), has questioned the provision of expensive #drugs to the very elderly because of the high costs for #society. This brings #eugenics back into the #political debate in a country in which arguments for improving national efficiency by eliminating what the #Nazis termed ‘useless eaters’ or ‘lives not worth living' once became the #scientific rationale for #euthanasia .
