ELI5: Why are carpet floors so ubiquitous in some countries? Are they worth all the extra hassle?

For an equivalent price, carpet brings more headaches than tile: stains are harder to clean, carpet wears down, fungus or other stuff can more easily grow in it, vacuum cleaning is mandatory—cannot just sweep a broom over it, cannot wash it with a mop. 

Coming from a country where tile/hardwood is the absolute norm, I'm still struggling to understand.

I'd say the main two reasons are warmth and comfort. It's much more pleasant to walk on without shoes/slippers because it's soft, and warm. It also keeps your room warmer since it helps further insulate the air from the cold ground (unless you have underfloor heating, of course). Lots if people also find it a makes for a more pleasant environment since it helps to absorb sound so rooms feel cosier since there's less echoing of noise.

I'd also say that vacuuming is easier and more convenient than sweeping/mopping to be honest...
