> * British Columbia punishes renters, as it taxes 'passive income' (i.e. rent), which discourages owners from renting out existing properties or building-to-rent.*
There are so many incorrect statements in this sentence, I don't even know where to begin.
Taxing vacant properties does not punish renters. It "punishes" people who buy properties for speculation, or (as the AirBNB trend is going) attempt to control a piece of limited supply.
The purpose of taxing passive income (lazy landlords, rent collecting) more aggressively is because it is not actually work. It is technically wealth extraction. As a renter, 100 percent of your rent is a "tax" (it's not going to offset any of your long-term assets); and when you pay 70-90 percent of your income in rent as a tax (as many minimum wage workers do), it is massively difficult, if not impossible, to save enough to acquire any assets that help you build wealth. On the landlords' side, it's even easier to use all that extracted wealth (from poor people) to acquire assets that build wealth.
No, collecting rent is not work or a job. Even if you have a whole fleet of illegal immigrants scrubbing the toilets, throwing down cheap carpet, and painting the walls of your units every few years. The moment you enter the territory of needing to pay somebody else to manage your asset (even if it is "just" scrubbing the toilets after your AirBNB tenants or renters leave), you're entering passive income territory.
