Relevance? It's a politics thread. The point isn't solely to highlight your personal success, lovely as I'm sure that is for you, it's also to discuss the flaw in the policy.
You'd say you've bettered yourself, but politely, as I see it you've not exactly pulled yourself out of the gutter by your bootstraps.
You were fortunate enough to obtain public housing and you've later taken full advantage of a right-to-buy at a substantial discount, which is fair enough.
You've also made a bit more than a 'few quid' out of it, again fair enough.
You're definitely personally better off, there's no argument there, but whether the policy makes the country as a whole better off is definitely debatable given the deliberate failure to replenish the public housing stock.
However it's pretty much the first time you've not accused someone of calling you 'immoral', which I can't see anyone has? That's what I'm 'on about'.
You're taking offence at something you're seeing which unless I've missed it literally isn't there. I could just as easily ask, what are you on about?
