Second, when you are subscribed to something in a certain amount of time you might not really use it as much as you thought you would. You might be too comfortable that the service is just there and easily accessible therefore not really making the most out of it. Like in a gym membership where you pay for the whole month but you only go for a few times.
Third, subscriptions are usually in bundles. There is no real transparency and you are not really getting a real breakdown of the costs. But we pay anyway. Are they actually worth it or we just do not have a choice anymore in a world where everything has to be subscribed to?
Electricity tokens, internet, and TV are starting to develop subscription-based features, even though they're used continuously. I see an imbalance in the aspect of gym memberships, where even if you don't attend, you still have to pay. While this system continues to evolve in our lives today, it's not always detrimental, as it can sometimes be quite advantageous compared to paying per session. Whether or not a system like this is worth it can be measured based on the amount of costs incurred, whether using a daily or subscription method, so we know the total amount.
I've also seen school pick-up and drop-off services that use a monthly payment system, and it's much more profitable for parents than paying daily. So, in certain contexts, the profit can be measured based on daily versus monthly expenses, so we know which is more profitable.
