Their other proposed solutions aren't accepted by politicians and the masses, because there's too many people benefitting from the system fucking the next generation to want to change it. We're literally living in the largest pyramid scheme ever constructed.

Renting only became a problem when it became a problem elsewhere... oh... well then it looks like it didn't work well did it.

If you're trying to imply that rent controls are good by your statement, can you show me anywhere that's implemented them that has affordable housing prices?

It's not like they haven't been tried, they just continually fail.

I don't see how this would make money laundering for organized crime any easier than it is today, the tax would just be shifted to the landlord side (likely at a higher rate since they're probably in a higher tax bracket) and off the tenant.

Right now the tenant earns money, pays income tax on that money, pays rent, and the landlord pays taxes on that money (if they're honest and report it all) but can claim their mortgage interest as a tax deduction.

I think the tenant should be able to claim some portion of their rent as a tax deduction. It would require an official record of rent paid, which would keep the landlord honest. I'd say the mortgage interest on a rental property probably shouldn't be tax deductible either, but even still this would have the biggest impact on those large private landlords that are often what you'd call slumlords.

Edit: I'm obviously not an expert on taxation or housing policy so if I'm wildly out of touch I'll accept that, I just think it's kind of bullshit that the government subsidizes the mortgages we pay for our landlords with the money we paid the government when we worked for it.

Like how Donald Trump does it?

Vacant House Taxes have been tried throughout Canada and are generally ineffective. They are just a distraction.

The main reason why they don't work is fairly obvious: Why would someone own property to keep it vacant?

Sure, there are some people with vacation homes, or second homes where they frequently visit (heck, I might have to get an apartment where my office is located now we're being forced to return to the office). Oh the Urbanity has a great video where they point out the vast majority of "Vacant Homes" are either students who don't permanently live there, in the process of a move, under renovation, etc.

Government can do this tomorrow but it will never happen.

He's regime whores who will do policy that hurts their owners.
