Let's take a look at some command economies: today: North Korea
In the past: The Soviet Union.
We can see that in both cases the countries failed to provide enough food and supplies for their citizens, so one way that command economies influence the citizens of the countries that had them was by inducing hunger. (the same is not true of mixed economies, or not always true).
Basically, the federalist wanted a stronger central government while the Republicans wanted a weaker one.
