Of the $32.653 billon in revenue Visa pulled in last year, 2.3% was network and processing opex, while 53% was pure bottom line profit[1].
Furthermore, squaring 17.9% tax provision line item: if your household had simple married-filing-jointly tax return with an AGI greater than ~$139.5k, you paid more in 2023 taxes than Visa...and that assumes you live in a state without income taxes.
Think about that for a hot minute while recalibrating expectations.
