Yeah what STP said was totally true, you really need to form your on viewpoint on the budget such as boris's succint response. When you analyse look at its effect on Eco activity, inflation, unemployment, income distribution, environment, CAD etc. Also you can look @ the micro reforms to improve the productive capacity of the economy and have a look @ there short term and long term effects in assisting achieving sustainble growth in the economy.
You have to also remember the budget doesn't just affect economic activity in the economy. The government can often alter resource allocation, income distribution as well as economic activity. Taxation and Spending decision can affect the demand/supply for a particular good and shift resources towards/away from a particular industry/good towards another particular industry. If you look @ the tax on pre-mixed alcoholic drinks you could argue that its destined to reallocate resources away from that industry by lowering demand for the products via the artifical increase in price. There's way more stuff you can talk about so yeah have fun
btw look @ the changes in Personal income tax to determine whether its made the tax system more progressive or regressive and argue what will happen to income distribution etc.
