Electronics don't get cheaper every year because the dollar strengthens. They get cheaper every year because the production process becomes more efficient. Some things can't really get cheaper every year (without some exogenous shock) -- anything with really high fixed costs of production OR a requirement of some level of quality by purchasers. For example, it takes a ton of land to grow corn. As the population grows, the demand for and value of land will rise. That means that for the farmer to keep growing corn on his land, instead of selling it or using it in a new profitable venture, the corn needs to be producing a higher level of income for him than it had previously when land was cheaper. Similarly - grass fed beef is not going to get cheaper. In addition to land requirements, there is the quality requirement also. If someone demands higher quality food, higher standards need to be followed, higher quality inputs need to be used, and a third party needs to ensure that those requirements are being followed.
