Mulroney did a lot of good things:
1.Supported Mandela at some personal cost to himself internationally.
2.Opposed the reintroduction of the death penalty.
3.Brought in the GST to replace the job killing manufacturer's sales tax.
4.Played a role in helping to mostly eliminate acid rain.
Okay, but you still have disastrous trade agreements, the unworkable constitutional proposals, the corruption, etc, etc.
I sense he is being facetious
It's a strong possibility.
Being a former economics student I disagree completely that the trade agreements were 'disastrous" except, of course, for chapter 10.
Meech Lake was a disaster and Mulroney's handling of it was even worse. "Seamless web" and especially "roll the dice" will forever tarnish his reputation.
I was a big backer of the Charlottetown accord and I believe had it passed several of it's proposals, especially the triple E Senate and the parts for natives would have been very positive. That said, it's failure to pass certainly didn't have the negative consequences that it's backers claimed it would, and it seems to be largely forgotten today.
