It's answer is a simple question why do we need to bother about money we gain it from work and use it to buy stuff easy as said. Especially in the case of going abroad, you often see the difference of currency between countries but have you often wonder why? Is it because our economy is low or whatever the reason maybe why is our value low. But if you truly go deeper in the matter you see the criteria of what makes a good money and how we can improve it. Think of it this way if we understand how money changes the economy, we get more incentives for example china there country was in a ditch before but because the government held and monitored the people's money the currency between it and other countries didn't increase much. And because of this look how far they are now. Money has a lot ways too be both useful and a simple piece of trash it all depends on how you contribute to make your currency/money a good one.
