It really depends on what you define as a luxury. How much is a pineapple in your local supermarket?
Back in the 1800's they were a luxury item reserved for only the wealthy because they were hard to transport from where they grow natively. They were so exotic that the middle and upper class would literally RENT pineapples for parties as a sign of wealth/prosperity.
These days thanks to modern refrigeration and distribution networks, the average commoner in many parts of the world can enjoy this delicious fruit (which I'll admit still tastes better when ripened on the plant before harvesting lol)
Yes, other "luxury" things like home ownership, travel, etc are becoming an unobtainable dream for many people in first-world countries around the globe.
But to the OP's point, look at other technology like satellite phones - once a mythical device mentioned only in fantasy novels a few decades ago and now many newer iPhones can send an SOS signal to overhead satellites and one can buy a bluetooth device so any phone can communicate with satellites (assuming you have a subscription).
Although if you look at things a different way, 100 years ago it wasn't uncommon for a horse to be one's primary means of transportation and an automobile was reserved for the wealthy. Now many people (in America) own a car (albeit often in rough condition, but still running somehow lol), but owning a horse is a sign of wealth haha.
