even now after hundreds of years when people hear the word "dollar" they still think there is only one dollar and that its related to america. they dont think about australia or canada or other countries unit of account of the same name.
Not even that, but most people throughout the world have minimal knowledge about the fiat monetary system that they use every day, that they are paid their wages in, that they save in, trade in, pay their mortgages in, etc. A lot of people don't understand basic concepts like APR, compound interest and inflation. I not infrequently hear young people talking about how they are stopping their pension contributions because they "need the money now, and I'll contribute in my 40s when my salary is higher so it will be fine" - completely failing to understand how compound interest works. People talk about receiving a 2% pay rise when inflation is at 3% - that's not a rise, that's a 1% pay cut.
Although I completely agree with OP that we
should be using these terms correctly, given that half the forum struggle to shill some worthless altcoin effectively, the confusion around these terms will continue indefinitely.
