When people have jobs, they will earn money.
The money earned from jobs will be spent so houses, cards food, and so on.
These expenditures lead to a growth in the business that supply these products and and create more jobs.
The Honda company can be used as an example. If people have jobs, they would be earning money and would certainly be inclined to buy a car. This in-turn would allow the company to thrive even more in Canada.
