Blame for what? The working class have no business looking to the left to get houses built. In what way does it "need" to readjust? No one's obliged to maintain the left's survival merely for its own sake. It's not a problem in the general sense, but a straight forward observation that the left's decline is intrinsic in its founding premises or ideals, such as "from each according…", as if needs and abilities have a meaning widely held enough to generate effective collective action. Whatever housing shortage one might entertain isn't a consequence of the left's flawed priorities, but our own unwillingness (or inability) to positively organise production and power.
