Eugenics received a negative connotation during the middle of the last century.
Are there possible eugenic programs which might gain popular approval?
Wikipedia mentions pre-marriage blood tests to screen for genetic incompatibilities which may lead to a high risk of birth defects. I personally advocate for the mandatory long term birth control or sterilization of felons convicted of violence crimes. (Perhaps multiple violence crimes would make it more palatable to the liberals? "Three strikes and we take away your bat!" ?)
