Ideally those tax funds would be used for public goods and services such as education, roads, medical care. Can check examples of countries with high tax rate but also high social welfare. But we know how inefficient and corrupt most governments are and without proper checks those welfare benefits are easily abused too
Either ways, there has to be some balance and anything extreme on either direction could be bad.
Idk about Canada but we do get $7500 tax incentive here in the U.S. so that has to come from
somewhere
