You have to compare apples to apples.
Besides that, that outlet in the home, the hair dryer has a built in breaker switch!

That outlet is
not a breaker. A GFCI will only trip if there is a short between ground and one of the legs. It may not necessarily trip due to high current--like a breaker.
The idea is that the GFCI will detect issues like if you drop the hair dryer in to a sink full of water (a hot leg will invariably get shorted to ground tripping the GFCI). If you plug two hair dryers into the same GFCI that GFCI won't trip but the 15A breaker its connected to will certainly trip (since a hair dryer by itself will draw around 12A).
