Regarding mutation testing, you don't write any "tests for your test". Rather, a mutation testing tool automatically modifies ("mutates") your production code to see if the modification will be caught by any of your tests.
That way you can see how well your tests are written and how well-tested parts of your application are in general. Its extremely useful.
Ah yes, advocating for basic human dignity is now "not understanding basic ideas about economics", and none of the SIX different solutions I provided (which I didn't invent myself, btw) could ever work in any capacity.
I won't be continuing this conversation, as it is clearly not productive.
I'm sorry, but you won't be able to convince me that allowing a single company to own hundreds of apartments is a good idea that won't contribute negatively to housing prices.
introduce a fairly high tax on every second (or at least third, progressively higher with each) property to deter buying up properties to rent
perhaps introduce another tax on properties which have been vacant for X months/years
introduce rent control
perhaps even introduce some form house price control (per square meter, tied to median wage, perhaps)
make the government build some housing
You can debate how well each of these would work, but there are many ways to bring prices down without making it less pleasant to live in those houses. I'm most partial to a progressive property tax, rent control and government housing, myself.
No, you're claiming that that's what I'm talking about.
What I'm saying is that making density even higher is not the solution to the housing problem. There are other, better ways of making houses more affordable than forcing people to live elbow-to-elbow with their neighbors.
About 10% of homes in the US are considered vacant, 5.5% in UK, 18% in Europe. 0.02% of the US population is homeless, I believe it's 0.006% in UK, 0.07-0.33% in European countries.
Yet your solution is still to make housing even less comfortable for poor people by getting rid of density laws and blame immigrants for the housing prices, to boot.
Saying "Airbnb" is obviously an oversimplification - a ton properties seem to be bought by rental companies, not normal people. There's a ton of properties just sitting empty, as well.
The solution is to introduce more control for housing, not less. Less control means more cheaply made hell-scape skyscraper buildings housing hundreds of people each, with no green spaces anywhere in sight.
Ah yes, let's make it even more of a hell to live in cities by paving over anything green and making people live like livestock in tiny cages. That will surely solve the problem!
Oh, and really it's the immigrants' fault! They're the ones buying up all of the houses with cash to later rent them as AirBnBs!
