Harper put billions into infrastructure, Trudeau should have left that alone.
Harper put in a taxable (making it progress) universal child care benefit, which Trudeau should have left alone.
Harper left Trudeau 2 years of balanced budgets and a growing economy that Trudeau should have left alone.
Trudeau is the poster child (just like his dad) of reverse Keynesian with massive spending and deficits during boom times when the stimulus is not needed.  This will will lead to massive deficits and debts with no money left when it is needed during the next recession.  
Trudeau is now trying to scrape every cent together, first beating up on those who create wealth with new higher taxes (as opposed to those who inherit their wealth), then trying to mug low-income retail workers demanding a share of their in-store discounts, and now, reaching the low of the lowest, going after those with diabetes.  
The man has no morals as he lays the groundwork for a destroyed Canadian economy.
