Who benefits from a weak U.S. dollar?

As a keen observer of the financial markets, I'm curious to know: Who stands to gain from a weakened U.S. dollar? The dynamics of currency exchange rates are often complex, but there seems to be a consensus among some analysts that a weaker dollar could potentially benefit certain economic entities. Could it be that exporters, who enjoy an increased price competitiveness in foreign markets, stand to reap the rewards? Or perhaps it's foreign investors, who find U.S. assets more attractive at discounted prices? What about emerging market economies, who often see a boost in their exports as the dollar depreciates? The question remains: Who are the primary beneficiaries of a weaker U.S. dollar, and how does it impact the global economy at large?
