While I'd love that to be true, economist's predictions don't have a good track record. Is there any good examples we can use to give evidence of thus massive claim?
If you want a more rigorous extrapolation, which tries to account for confounding factors and isn't limited to one pair of countries... you are going to have to look at the research (of economists).
You'll have to do better than that, because the majority of economic literature does not attempt to forecast movements, it attempts to model them and understand them. The "track record" you speak of is not actually the track record of economics, it's just a meme armchair economists like to repeat (generally without a non-snarky defense of their point).
