Look, I think you must struggle a bit with the ethics of the situation, otherwise you wouldn't have asked the question.
The housing market in the UK is undoubtedly broken, and it's historic, and complex, and the burden of blame doesn't fall solely on the shoulders of private landlords, but they are undoubtedly part of the problem.
And threads like this always only ever go one way. There's a lot of legitimately angry people out there who cannot get on the housing ladder because the market has been absolutely buggered by private landlords, and the political environment that allowed them to flourish.
We can't compare the UK private rental market with Europe, for many reasons, so it's pointless to try and do so, they're very different things.
And there most certainly is a need for rentals for a dynamic workforce amongst other and varied reasons.
It's inescapable though that private landlords, for the main part, in the housing situation we currently have in the UK are unethical.
And when they appear on threads like this to extol their virtuous and altruistic nature, and also claim that tenants are destructive beasts that have taken advantage of that and destroyed the homes that they were so generously providing.
Well, people are going to be pissed off aren't they?
I sometimes think that landlords are not only unethical in their investment choices, they're maybe masochists too.
Why else would they post such blind nonsense?
