It is not the same all over the world. Starting a small company in the US is a breeze compared to what I’ve watched peers in the EU fight against.

Interstate commerce also seems to be vastly easier inside the US in comparison to the alleged single market of the EU. The most companies seem to deal with is California-specific regulations. Meanwhile, most companies in the EU eventually opt to create a ton of subsidiaries, basically one per state, to handle all the localized duties that the EU requires.
