Get educated on this.
True - the Soviets did NOT invest so much money into the "special needs" as the US does (very inefficiently, at that).
Nor would they try to save an unhealthy child at all costs (of course, the technology was not quite there either).
(Per my observation, the current system in the US is not sustainable; it will crash and burn; amount of special ed support personnel/programming in the general schools is just not sustainable when practice on person-by-person basis without much consolidation).
Instead, they institutionalized the special needs into few centralized places - less human, but much more efficient and cheap.
For example, any kid in my village of the USSR era was sent off into a regional institution where they received specialized care and specialized education.
But this could be less human (unless the parents are alcoholics, then maybe the institution is MORE human????).
Add the corruption into the mix (where allocated funds get stolen away) - which makes the institutions even less human (like starving the institutionalized persons, simply put).
That's the brief Soviet recourse.
