Legacy. Empire. Providing for your children's children. Giving your loved ones the kind of life they've never even considered possible. Seeing the smile on your mother's face when you get to tell her she can stop working, that you've taken care of her and your father, and your brothers and sisters.
The 1% are living in a way that will last longer than they will, on a scale that the rest of us won't achieve in our lifetimes. That's okay, certainly, but to pretend like there's no reason to work towards the 1% is silly.
Maybe you are thinking of the 0.01%. The 1% income threshold in the U.S. is about $380K. That's wealthy but it's not empire-building. Most senior software engineers are probably in the top 5% of income earners in the U.S. already, they could easily be in the top 1% with a high earning spouse.

It's $521,411 per household[0] (the household bit is probably where we're getting confused).
$500k, $400k, either way, the goal is as I've stated; once you've taken care of yourself, you start wanting to take care of others. There is always motivation to make more, until everyone is provided for, and even when you've provided for everyone you care about, providing for the general wellbeing of humanity becomes a priority (Gates, Buffet, et al).
'My name is Ozymandias, king of kings:
Look on my works, ye Mighty, and despair!'
Nothing beside remains. Round the decay
Of that colossal wreck, boundless and bare
The lone and level sands stretch far away.
One possible explanation for that is that there are two kind of people, some who believe that everybody is working towards the same goal and some who believe that everybody should decide what their own individual goals are. The former group settle on money and social status as those universal goals, because they are reasonably common and can often (though not always) be exchanged for what you really want. The latter don't believe in telling other people what their personal goals are, because if they are different for every person, what's the point?
Under this model, 100% of the public discourse would be devoted towards achieving money and status. That does not mean that everybody (or even a majority of people) pursue those goals, only that people who do talk about it a whole lot more than people who don't.
And what, exactly, is it that you're losing? You can have a pretty damn fine life without getting anywhere near the 1%.
