Dude if US is overhyped and running on empty bubble growth then almost no country on earth can claim to be running on more tangible growth..
You do realise that the US tech dominates or plays a mohor role in almost every major sector right? From aerospace, to software to finance to entertainment to semiconductor to operating systems, Internet industry( they invented the damn thing anyway) to media, to space Industry etc etc..there are many more..
In short if you claim US is all empty bubble then which countries you think has real growth? Russia, Iran, Venezuela or?
Of course I understand you are biased against the U.S( even a blind man can see this on here) for obvious reasons( since you know they are against your country), but that doesn't means you should just parrot anything that comes to mind. At least you can use more viable reasons to justify your bias and point of view which can be more believable even to those who are neutral.
