Ahh.. well, inflation is often called the tax of the bad governments. While not being properly a tax, inflation is based on a monetary effect, but it is also linked to the rest of the world. Let me see if I can do the six year old explanation to this one:
You produce apples. dumBAss also produces apples.
You have 1000 USD and 1000 apples this year, so your apples cost 1 USD per each.
dumBAss does the same, he uses BAcoins and has 1000, so apples are 1 BAcoin.
The exchange rate is 1 BAcoin = 1 USD as both buy you 1 apple.
Hoewever you are far smarter than dumBAss (not surprising), so you manage to increate the productivity of your economy and, with the same effort, you now produce 2000 apples. Salaries remain stable, so your citizens now have twice the number of apples to eat.
Your economy is much better than the one in BAland (not surprising), so you can now sell apples at 50 cents. The poor citizens of BAland now can buy an apple for 1 BAcoin or for 50 cents. So now the exchange rate is 1 BAcoin = 0.50 USD.
dumBAss is now worried. While he was immersed in his Biblical studies (of the wrong short), your apple industry is much cheaper than the one in BAland so he asks his friend Trump for advice and Trump says "make BAland great againg by puting import taxes".
dumBAss puts a 100% tax on apples, so now your apples sell in BAland at 1 USD.
Thus, the citizens of BAland now pay DOUBLE than your citizens for the same apple. That is what I would call a hidden tax. Not very well hidden, but hidden.
The coin of your country is stronger, it buys you 2 apples, a BAcoin buys only one. Do that a few times and BAcoin will be worthless due to inflation.
