English has all manner of ways around the fact that we abandoned plural "you" around 1600 or so. Y'all, yinz, you-all, you guys. I grew up in the South, so it's "y'all" for me, but there's nothing fundamentally wrong with "thou/thee" for singular and "you/ye" for plural second person. It just was victim to the euphemization treadmill until it fell out of common usage, so we had to reinvent it.
