| Oh you were talking about credit cards? Well, that's another whole can of worms. Virtually no retailer in Germany accepts credit cards because the fees are too high and price competition in Germany is pretty brutal (just for reference: Walmart, which steamrollered US retail had to retreat from the German market, in part because they simply couldn't compete). So you are paying for these services, and yes, cost of living is higher in the UK, for example: https://www.numbeo.com/cost-of-living/compare_countries_resu... Oh, and the terms imposed on retailers by credit card companies are pretty brutal, too. For example, they push most of the risk of fraud onto the retailer. If you think that doesn't matter: KAGI went out of business due to fraud. https://tidbits.com/2016/08/04/kagi-shuts-down-after-falling... So what's happening when the purchase is "taken off" your credit line is that the retailer gets hit, doubly, meaning they have to raise prices on everyone to stay in business (see higher cost of living above) or they go out of business (see KAGI example). German retailers don't want this and German consumers don't want this either. And of course the credit card companies have managed to create a tax on the entire economy, essentially a rent-seeking/parasitic business model, while pushing all the cost and risk onto others (the general public and the retailers). Now if I were a credit card company, I'd be all "Yay!". As a consumer or a provider of products and services...not so much. And again, the convenience, while shiny and cool, is at best trivial, and I would say offset by other conveniences such as haptic processing, fungibility, loanability ("Quick, can you loan me €50?", "Er, here's my card?"). And there is significant added complexity in the system, which can fail fairly dramatically. For example, when I was in living in the UK my UK card would not work just about every time I went abroad. "Fraud protection". Hah. I've had that happen a lot more than I ever had cash lost or stolen, and the consequences are more severe. The bank suggested I should contact them every time I went abroad. Excuse me? I need to ask my bank for permission to travel? That's one thing that's also a very important lesson for software, particularly performance: in almost all cases, resilience is more important than (peak) performance. You really want to strive to avoid bad outcomes, not make the already good outcomes a few percent better. This is harder, but more worthwhile. And of course the point of credit cards is to get you to spend money you don't have, which is also why eliminating that haptic feedback of money leaving your wallet was and is so important. And surprise, surprise, credit card debt is (shockingly) high at least in the US and the UK. So don't get me started on credit cards :-) |
