Step 4 was implemented in the USA with SSDI. There's heavy emotional baggage to tag people as permanently totally disabled merely because the economy is too small to let them participate. Also its kinda a mess mixing essentially fake claims (from a medical disease perspective) vs real claims. So the same program takes care of a guy with 100% disability back pain who sells his pain pills (a whole nother problem) and plays video games all day but is actually physically healthy while merely economically dead, with another dude missing some limbs or brain damaged. Its weird but mostly seems to be working rather than your step #5. Around 1 in 20 people in the USA are on SSDI. The exact ratio of who's economically damaged vs physically damaged is unclear but you can guess by looking at rate graphs over the last couple decades, since the 80s perhaps.
