"In other words, a wealthy citizen in Québec pays more tax into the federal system and funds more equalization than a poorer citizen in Alberta"

Except there are a higher proportion of wealthy Albertans than wealthy Quebecers, and a higher proportion of poor Quebecers than poor Albertans, hence the average Federal Taxes paid by Albertans is higher than the average Federal taxes paid by Quebecers.

Net net Alberta pays more in Federal Taxes than it receives n Federal programs and transfers, Quebec receives more in Federal Transfers and Programs than it pays in taxes.

Ain't Canada great!
