>Simply put, universal high income is a universal basic income that is high enough to be considered "high." Universal basic income is not a low universal income.

Isn't the difference that with UBI you still need to work for money to have a reasonable life filled with joy and peace of mind. Contrast with UHI where, presumably, the income is so high that you do not have to work but can still enjoy the "luxuries" of joy and peace of mind?
