“Stop paying cash for a discount,” he has told taxpayers. “Because you are effectively cheating the system or helping someone else to. This is not a victimless crime. If you pay cash for a discount, in many cases you are effectively ripping off yourself as an Australian taxpayer, because this type of behaviour is what sees billions flow out of the tax system and into the cash economy.”
Hmm, that is not how finance works.
a) The difference between cash & credit is the difference between paying interest (on the credit) plus admin costs.
Credit in NOT free & for many people is quite expensive. Poor people don't have access to credit.
b) The tax arbitrage between the cash & credit payment (unable to write off the price of credit) is the arbitrage opportunity. An arbitrage opportunity to those who have access to credit & necessity to those who don't have access to credit.
Next one.
