I am not 100% sure of the answer (I am sure there are websites where this is explained), but I am reasonably sure it has to do with the fact that V and U used to not be distinct letters, but variations of the same letter.
I find both of those names silly, I like the fact that my first language (German) doesn’t call any letter “double” anything.
I am not American, but Austrian. I earn way more money than I spend each month, causing my bank balance to rise over time; I am not going to say exactly how much I have, but €1000 (which is about the same as $1000) is no problem for me to afford when I need it.
While it’s better than the alternative, it still doesn’t make me very happy because this only helps fulfill the bottom two levels of Maslow’s hierarchy of needs. I wish I could easily earn less money, but have more free time to travel and pursue hobbies, but the system of wage labor is not flexible enough to cover the needs of someone like me.
