1. Regulated Capitalism
2. State Funded Infrastructure.
ad 1) Capitalism isn't a bad system per-se, but needs to be kept in check. States need to ensure that un-competitive behavior is kept in check, that too-large monopolies are reigned in, that consumers are protected, that fair taxes are paid and that private wealth has no undue influence on politics.
ad 2) Structural systems required for a society to function properly have to be, at least partially, state funded, state controlled, or even state owned, thus ensuring the availability and baseline quality of structural services to as many citizens as possible, with regard for revenue generation being a secondary concern.
