[19] Sweden was the first European country to print and use paper money, but it may soon do away with physical currencies.
    Banks can save a lot of money and avoid regulatory headaches by moving to a cash-free system, and they can also avoid bank robberies, theft, and dirty money.
    Claer Barrett, the editor of Financial Times Money, says the Western world is headed toward a world without physical currency.
    "Andy Holder—the chief economist at The Bank of England—suggested that the UK move towards a government-backed digital currency. But does a cashless society really make good economic sense?"
    "The fact that cash is being drawn out of society, is less a feature of our everyday lives, and the ease of electronic payments—is this actually making us spend more money without realizing it?"
    [20] Barrett wanted to find out if the absence of physical currency does indeed cause a person to spend more, so she decided to conduct an experiment a few months ago.
    She decided that she was going to try to just use cash for two weeks to make all of her essential purchases and see what that would do to her spending. She found she did spend a lot less money because it is incredibly hard to predict how much cash one is going to need—she was forever drawing money out of cash points. Months later, she was still finding cash stuffed in her trouser pockets and the pockets of her handbags.
    [21] During the experiment, Barrett took a train ride. On the way, there was an announcement that the restaurant car was not currently accepting credit cards. The train cars were filled with groans because many of the passengers were traveling without cash.
    "It underlines just how much things have changed in the last generation," Barrett says. [22] " My parents, when they were younger, used to budget by putting money into envelopes—they’d get paid and they’d immediately separate the cash into piles and put them in envelopes, so they knew what they had to spend week by week. It was a very effective way for them to keep track of their spending. Nowadays, we’re all on credit cards, we’re doing online purchases, and money is kind of becoming a less physical and more imaginary type of thing that we can’t get our hands around."
