You write that as if a normal persons life isn't fraught with challenge or that living should be easy. This is a slippery slope to say nothing of the stop all medical progress would gradually make in understanding these conditions as policies to encourage this would proliferate. When one goes down this path of eugenics, you eventually have the state taking license to define who is deficient and who isn't, not a particularly appealing thing as governments are generally monstrous organizational entities hell bent in manipulating and controlling their people. All you'd need is one person to interpret or rewrite existing policy to enable them to sterilize or execute the parents as well for carrying the genetic "deficiencies" which led to their child's condition for life to really get challenging.

Perhaps the next person fine tunes that system to cull obviously "deficient" individuals, they'll want to keep the program operational and funded, so they'll justify expanding the criteria of termination eligibility. Soldiers returning from war with physical and mental injuries would be denied physical, psychological/psychiatric service with the state showing a marked preference for quick, expedient, and cost effective alternative in euthanasia. Children who fail to perform at certain levels of proficiency would be identified in school, more closely scrutinized, and marked for later sterilization, or termination, if they don't accomplish a minimal level of achievement by a certain age.
