China had a ~25 year head start.

A lot of the work going on currently (rail electrification, dedicated freight corridors, highways, deep water ports, etc) will pay off in the future.

Where do you live? The city I live in was connected to the next city via a two lane road. Now it's a 6 lane expressway way with service roads on either side.

The infrastructure between cities, including roads and airports has been drastically improved in the last ten years.

The cities themselves are not improving at the same pace. Corruption, especially in the money making states like MH and KA, is still rampant.

China is in its own league but a decade is roughly right. Dive into it a bit, there’s a lot of good going on and I’m a cynic.
