my ex worked at South cambs council and when the tenants done right to buy, the value they payed was well expensive and not dissimilar to non-council houses for sale in the same areas. alot of the tenants used to go ape and demand re-valuations etc, which often valued them even higher haha
its a welfare state so these things do go on, i'd rather there was some kind of welfare system than none at all. cos its "well fare" haha. unfortunately there will always be people who abuse the system or think that the state or others owe them a living. not all of them are like that though.
