If you are from India and reading the heading then you will be thinking what nonsense is this. Just now GST has come and you are started paying more already. GST is also expected to bring down the cost/tax eventually. Topic is not about GST or India alone.
This is about how technology innovations will transform and redefine many industries globally. Some counties may see this transformation little later but eventually most countries (developed and developing counties for sure) will experience this.
While the technology is exponentially growing and the impacted areas of cost is going down every year. Most of the areas costs are going down – Transportation, Healthcare, Energy, Telecommunications, Hardware, Software, Entertainment, etc. Eventually costs of living will come down.
Uber reduced cost of transportation. iTunes revolutionized music industry. Airbnb redifined hotel industry. 100s of such examples. Each one of such innovations are indirectly trying to bring down the cost and increase the quality. This is still beginning I would say. With advancements in AI, VR, Robotics, 3D printing, etc you will experience the world with much cheaper cost. Not just you also billions of people across the globe ( real equality and democracy).
Fast forward 30-40 yrs (may be sooner). All these will be real and most importantly cheaper.
