OK, I admit defeat.
Your comments made me do some actual research. I admit, I simply dismissed many of these types of comments because I assumed (voilà the problem), that there were very few boat manufacturers in Canada that sell such boats above 250k. As I delved into some articles, I found an analysis done by Jack Mintz. I verified and yeah, he's an actual economist, with actual vetted academics and real world experience. His report,
Economic Analysis: Proposed Luxury Tax On New Boats Will Be Job Killer & Have Major Negative Impact on Boating Sector , evaluated the possible impacts of this tax. But it does state in the report the impacts are highly dependent on an "elasticity" number he uses to forecast the possible severity of the problem. Nobody knows that number exactly for Canada... yet.
I'll spare everyone the details because I'm probably the only one stupid enough to get sucked in to reading such a report. But yes, the effects to the boating industry, dealers, workers, service industry, most likely balance any net gains from the tax. In essence, it seems it's to portray the government as taking from the rich to give to the poor. I personally couldn't care less about that last statement, but I get that those optics look good to many people.
I still don't think the people buying those boats will be hurting by this, but yeah, it does hurt others enough that I'm fairly convinced it's not really worthwhile. Better off doing other things to get this money.
I also came across multiple sources about the USA luxury tax failure that you mentioned along with other countries too. Each time, the rich people avoid it, postpone purchases, etc. until the tax is taken away. In the meantime, hurting those industries.
Yes, for those wondering, people that admit they were wrong do exist. lol I like to base myself on facts in life. I reserve the right to change my mind when I learn new things. Just like I reserve the right to change my mind again if I learn new things that oppose what I just discovered. That's right, that's my future "out" in case I need one.
