Heres how i understand things:
Balancing budget and paying own debt have 2 sides: decreasing government expenditures and increasing revenue. Revenue is collected by the government in the form of income taxes and sales taxes. A healthy economy generates a larger revenue stream.
Hudak seems to want to balance the budget and pay down debt by decreasing expenditure. (cutting back programs and laying off government employees) He's getting ahead of himself when he promises lower taxes, because that's the revenue stream side. He believes that lowering taxes will stimulate economic growth, but there's no guarantee that (multinational) companies won't simply pocket the difference to pay dividends to their shareholders, and Ronald Reagan has already demonstrated that the trickle down experiment didn't work except for making the already wealthy investors/shareholders wealthier. Laying off 100,000 well paid civil servants (teachers, nurses, firefighters, paramedics, etc.) is certain in his plan, creating new jobs with lower taxes is uncertain. If the economy falters, balancing the budget and paying down debt becomes more difficult because of the reduced revenue stream.
