The Canadian government has been carrying a large amount of public debt, and researchers wanted to see if it's too high. They used a model to study how public debt affects people's well-being. They found that if the government spends money on things that don't help the economy, it's best for them to save money instead of borrowing. Even if the government spends money on useful things, like public goods, the debt is still too high, but not as bad as before.
