My little system has +9 tech level, +7 development, +10 security, +1 wealth, and +14 quality of life. Obviously, a dump.
There's this line of thinking in the other thread that wealth and QoL( or was it Standard of Living) ups the demand for goods in the system. But your QoL is quite high by itself already

I'm going for medium security for my little system - smugglers need to make a living too
