Honestly, that protruding rebar reminds me of the common practice in some Central American countries of pouring the columns and crossties for the first story and leaving rebar stubbed out the top for a future second level which may or may not ever get built.
Oh, that’s a common thing all over the world - it’s generally because property taxes aren’t payable on incomplete structures. Seen it everywhere from Bulgaria to Cambodia to Egypt.
That's a myth, albeit one commonly held everywhere, even by locals.
You don't find it odd that so many poor- and middle-income countries with wildly different legal histories and taxing structures have the same glaring property tax loophole? Despite often wildly different origin stories for how the loophole came about?
Yes, some jurisdictions tax incomplete structures differently, but that only begs the question of whether a habitable structure lived in would be considered incomplete merely because some rebar is sticking out.
The real answer mostly relates to patterns of savings and real estate finance. In places where people invest their savings into their home directly, without a mortgage or similar as is common in more developed countries with robust retail financing options and comparatively liquid real estate markets, they often plan to build incrementally over time. Today you have enough money to build a 1-story out-of-pocket; in a few years you hope to have enough saved to expand to a 1-1/2 story or 2-story. This is much more feasible with concrete construction as it's relatively cheap (if not free or even cheaper than finishing) to just leave rebar exposed. Of course, as you pointed out earlier this doesn't make for great engineering. So you're more likely to see this in areas with loose building codes or lax enforcement.
In really poor areas you'll often find partial structures that aren't even habitable. That makes no sense in the tax loophole theory, but perfectly fits the theory that these structures are methods of investing savings. What's sad is that it's not uncommon for these to sit unfinished (to the point of habitability) for many years, or never finished at all; hard-working people's savings effectively lost.
