There are a lot of working poor and lower middle class who grab onto taxation myths. A friend of mine willingly worked overtime for his company, but refused the time-and-a-half overtime pay because he believed he would get less money on his weekly paycheck. I couldn’t convince him otherwise, the overtime myth was so well ingrained.
Canada top marginal rates are 50%, which comes in at $200,000 a year. Maybe 3% make this income. I don’t see them withholding their services because they are taxed so high.
