Why did they need 60hz? Why not 50 like Europe? Is there some massive advantage to syncing with the ac frequency of the local power grid?

If you’re used to seeing 60Hz everywhere like Americans are 50Hz stands out like a sore thumb.
But mostly I suspect it’s just far easier.
Conventional wisdom a few years after the Macintosh was that 50Hz was annoyingly flickery. Obviously this depends on your phosphors. Maybe it was already conventional wisdom at the time?
I feel like the extra 16% of screen real estate would have been worth it.
A white background at 50hz was pretty flickery, at least to my NTSC-experienced eyes, on a TV. Maybe they could have used longer persistence phosphors in their monitor, but then motion and animation would blur.
Speaking of phosphors, early Photoshop had a setting to pick what you were using. These adjusted RGB balance according to published or measured values. https://twitter.com/gingerbeardman/status/154371808662010265...
