Unfortunately, that is how inflation works. The price of goods, products, and services will inevitably increase/decrease depending on the economy of the country but salary must follow to the change in order to cope for it. Applying cryptocurrencies, these can be either short/long-term investment depending on your goal. If you want your kids to benefit from this change, better save-up some bitcoins!
Not just inflation mate, there are sevral other factors that lead to why people cannot cope with the rising value of many of the muh needed goods around us. Some countries even have a steady increase at salary rates, but still, there are some people who cannot seem to get a break. I think there are two views in this, for poor or borderline poor countries, it is about the low amount of salary people have, it is just too small, but many of the companies there cannot give them more because that would put them under the bus. For richer countries, I think it is just with he way they view and spend money, they tend to spend more than they earn, but they cannot seem to see that.
