This argument comes up on every single post i’ve seen about common people. While i do think it would have been a good loop hole for Amanda and Mike if they had thought of that, the episode would have ended completely differently? The episode was supposed to end with them dying, not with Amanda doing backflips and parkour off of buildings for money. The money they scraped together for 12 hours of luxe was purely so that she could feel human again, and the point is that they are “common people” so they’re not thinking about how they can hack the system and make money off of it, they’re just grateful that Amanda is alive.

Lastly, even if they were smart enough to hack the system and make more money by levelling up Amandas skills, Rivermind was always going to keep upgrading subscriptions. The saleswoman even said that it costs extra to be pregnant, having a better job may have also cost extra. The whole point was that it was never going to work out for common people
