Hopefully the audience she addresses is young enough to not remember the last time the NDP were in government. It was an economic disaster.  Increasing taxes and the public sector is not sound economic policy.
What the NDP fails to realize is that business exists to make a profit, not to create jobs. More importantly, it is the resource sector and private sectors that create wealth, not bigger government.
Maybe they will her how the government intends to pay for $10 daycare if the surplus has already been accounted for. She can always say that budgets balance themselves. It worked at the federal level.
