Obviously, even economists don't agree on the percentage at which tax reductions become self-financing. Is it at 100% or partially? Fortunately, taxes such as the capital tax no longer exist. The impact of that tax was greater than 100%. Its elimination more than offset the loss because it was such a bad tax.
We have to be competitive. A number of countries, including social democratic ones like Sweden, recognize that low corporate tax rates are important for economic growth. They have rates that are comparable to Canada's, if not more competitive than ours.
