I read some articles before and today I tried my way and it worked. Maybe someone has already mentioned it before but I still like to repeat it.
1. Adjust tax so that you only tax on imports, exports, and goods(under sales tax, ignore sevices tax). You need to tax the three as much as possible. Leave other taxes zero.
2. Adjust the markup of somestic sale price as high as possible except food and water, the latter set as -50%(Because you have already taxed 50% in step 1 and now refund it back so that you would keep the price of food and water as low as possible. Put all investment slide to the left.(you should not take any burden of the produciton).
3. Change the production as 100% of "demand" instead of "capacity" except of cosumer goods, which is the only important engin to drive your economy(But not too much, it depends on how much markup you set, you can see what I was doing if you continut to read). Don't rely on the world market because of your cost.
4. Export nothing and import as needed.
Now, you transfer all the inflation effect to your people! Now, you will have piles of money and try to double all budget as you wish.
Weird. One time I made a trillion of dollars, one time I lost and died of starvation and cannibalized by hungry citizens.
However, are you sure that it won't collapse after a while. Inflation was 51% either way!
EDIT: with coal and uranium in plenty and in surplus, and the rest atrophying to high costs, this makes a billion cash every day, however rich countries still need some poor and medium taxes and 15% business tax to work healthily.
Dude, I'm racking up billions! Gadzillions and lots of research!
