From their point of view it might be quite a good trade-off, because they probably think it's far more useful for them to spy and hack US and UK citizens than it is for China and Russia.
And they also probably think that they, the elites, could use something better than what everyone else uses, too. So there's no negative to this.
Nobody would call the US an "empire" if all it did was keep in its own territory and stay out of other country's internal affairs. Nobody calls Canada an empire for example. But the US keeps deciding to outright attack other countries or uses the CIA to subvert internal politics (and sometimes to overthrow democratically elected governments e.g. Iran).
The US deserves to be accused of having imperial intent, even if just based on their interest in other country's oil.
The word you're looking for is "imperial." "Empirical" means something else entirely.

America has had the most powerful military on earth for 70 years, along with a large population. List all of the vast amounts of territory it has annexed using that extraordinary military power. There are endless opportunities to do so, and the US is the sole military with global projection.
Some people point to military bases. Which doesn't work in any regard. A few critical differences being: taxing power on the local population, or vast plunder. Neither of which America is known for. And US military bases around the globe overwhelmingly exist by permission.
Controlling territory but not extracting wealth is pointless. The U.S. doesn't extract wealth from its foreign bases; in fact it injects wealth because the bases are paid for by U.S. dollars but the downstream spending goes into the local economy.
And you might think "well the U.S. extracts the wealth through trade." But trade is mutually beneficial (unlike taxes) and the U.S. runs a foreign trade deficit anyway.
The things that the U.S. gets for its projected power are peace and stability. These are things that benefit any nation, though.
Hence we get scenarios where China is claiming islands a thousand miles off its coast as domestic territory and while the US Air Force flies overhead and Obama tut-tuts the whole thing is a boundary pushing exercise (no pun intended) and China continues to do what it wants, within reason. China knows that shooting civilians as in Tiananmen Square in 1989 makes for very unflattering optics and jeopardizes the Western trade and investment it needs.
Every day articles and blog posts announces the imminent demise of US and Western power or China's impending economic collapse. It's possible of course but for the moment not very probable. But it is clear that the West is no longer *utterly dominant.
Economically, militarily and culturally they are, what metric are you using?
