Sure there's a handy list of suggestions but also a page to write in your own.
Sven at Fish Eggs has an idea :
"Every Canadian Citizen, will, for the next twelve months, receive a $2000 monthly payment. If you make more than $35,000 per year, it will be progressively taxed to ensure it gets to those whom need it the most. Simple.
This programme will run for one year only. Short.
As the lower income earners all know, this money would enter the economy almost completely, as there is little or no room for most to squirrel away their money. People could spend this money to buy a car, thus bailing out the auto industry. Or they could choose to spend it on housing, thus bailing out the housing industry. Or they may decide to invest in more education and go back to school, thus bailing out the education sector. What matters here is that the PEOPLE would decide where to put OUR hard earned tax dollars. The politicians would then be able to see where we chose to put our money and they could then craft legislation to reflect these investment choices made by Canadians. Effective."
Go for it, Sven.
