at least one of these measures work, take a look at Portugal .
Since April
last year, the Portuguese government has been running a raffle for people who
demand receipts for the goods and services they buy, thereby forcing those
businesses to pay value-added taxes. The result? More than 40 lucky Portuguese

more than 4%, or €563 million ($611 million), while private consumption rose
just 2%.
