It's not totally a "decision" on the part of the Americans to use a lot of wood in construction. It's just that America has tons of space, including space useful for growing Douglas Fir and Southern Yellow Pine, which then can be turned in to 2x4s and other construction lumber.

Most of Europe long ago exhausted easily accessible natural forest resources, and where it's not densely populated tends to prefer using land to do other stuff (like grow food). Hence, stone and concrete and similar materials in European construction.

That “Europe” doesn’t use wood in construction is news to me.
