I got curious while reading and I've read this[1]:
> Revenue is total money from core business activities before expenses are deducted.
> Income, or net income, is earnings remaining after all expenses are deducted from revenue.
Sorry for being pedantic. I don't understand why English has such ambiguous terms for something that shouldn't be. Or am I even more confused now?
To directly answer your comment: I agree that companies should be taxed on revenue and not income. Citizens are taxed on revenue, so why aren't companies?! They're supposed to be treated as people.
