>IMO official numbers dramatically increased
By dramatically increased you mean went from 1.8% during a pandemic when people were afraid to move around to 2.5% as things eased, well in line with historical levels.
I think the OP is much more accurate with the statement "the idea that employees are quitting in droves is exaggerated".
In fact, if you look back more than the year you picked, you'll see there was a huge drop, and the current blip is most likely those people feeling some relief from the pandemic. The rates are no where near out of line historically.
Here's historical data graphed for all 4 regions you listed.
