I mentioned it as all else being equal. State Enterprises increase the wages of state employees, so I imagine that’s one way how they increase GDP (asides productivity). They are massive stimulus packages, just their effects are not entirely how we would expect them to be in the real world.
Full employment would also prevent hiring, so it’s not preferable for an economy.
Yes, I could look at all the values which increase disposable income in game, but it would be easier, if Cliff could write the formula here, with a legend for all the inputs.
