Look, I think the worst case scenario is obvious. I think first of all it doesn't work for very long. It's an unstable government that raises taxes and destroys the image we're building for Canada as a strong place to invest.

In this quote, Stephen Harper is expressing concerns about a potential government policy that could undermine the economic stability and reputation of Canada. Harper suggests that if the government raises taxes excessively and adopts policies that destabilize the economy, it would harm the image Canada has been working to build as a strong place to invest. He views such actions as potentially leading to economic instability, which could erode public confidence and discourage investment in the country.

Harper's warning reflects his belief that certain government policies, particularly those that involve raising taxes or expanding the role of the state, can lead to negative consequences for the broader economy. He argues that high taxes could reduce the country's competitiveness on the global stage and make it less attractive to both domestic and international investors. This could ultimately slow down economic growth and hurt Canada's position in the global market.

By calling it an "unstable government," Harper is critiquing the approach of governing in a way that undermines long-term economic health. He suggests that such a government would be unable to maintain stability over time, and it could create an environment of uncertainty that damages Canada's reputation as a reliable place for business. For Harper, the stability of the government and its policies is a key factor in maintaining investor confidence.

Ultimately, Harper’s quote reflects his conservative economic views, advocating for policies that prioritize fiscal responsibility, lower taxes, and a stable, business-friendly environment. His concern is that policies that disrupt this balance would be detrimental to Canada's economy and its standing on the international stage, particularly in terms of attracting investment and ensuring growth.
