This is interesting, in that I've tried to come up with simple simulations like this for strategy games before. But I was a little "eww" when he kicked the number of government workers up to 40% of the workforce. Looks like it goes all the way up to 50%. On simulation #13, where tax is fixed at 10%, the government workers all eventually starve. Surprisingly, the libertarians are correct because at this point the qual…
That's because on this simulation the government isn't doing any useful work.
The ration tickets work because the people were programed to actually follow the law. It fails every time on the real world because real people aren't.
And the simulation #20 works because the simplistic model actually works. At a first approximation, inflation isn't a problem at all. Things only start to fail after you have competition, corruption, very limited resources, etc.
Simulation #21 is a great visualization of why people must be able to set prices with enough freedom, and why forced price-fixing bankrupts countries.
