And worldwide young people struggle leaving their parent's house because they can't find an affordable place to buy or rent
Almost every issue right now follows back to there's not enough houses and now it's starting to affect society with radical left leaders getting elected
They almost certainly have the wrong solutions, but they 100% address the right issues
Almost everywhere in the world we should be agressively building more homes and making it easier to do so, so everyone can afford a roof above their head

Build more homes for everybody!!!!
