Tolling is the perfect example of taxation that unfairly targets the poor. 

Here in Vancouver, which has the most unaffordable housing vis a vis income in North America, working families have fled to other cities in metro Vancouver or the Fraser Valley. These areas have few to no viable public transit options.

The cost of commuting has risen for these workers, so what is the government solution?  Make them pay more toll and road use charges. 

Meanwhile the rich who have the millions to buy a home in the city of Vancouver, still get to drive around town in their luxury cars (Vancouver also has the most luxury vehicles per capita in North America), and avoid the majority of road use tolls. On hopefully, roads that will have fewer vehicles to impede their way.
