As always, our politicians only tell us half-truths. Yes, the tax RATE for middle income earners was dropped by Justin & Bill.  However, many middle income families are now paying more in total income tax than they did before the rate cut because Justin & Bill did away with other income tax benefits they previously received. So, yes, it is true that middle income earners are paying a lower tax RATE, but they are not necessarily paying less total income tax - they are in many cases paying more.
