Talking about Barcelonas and most cities’ gentrification problem, it’s not capitalism is what I meant for “blaming the system”. Then the other was regarding “regulation”. The incentive could be elsewhere instead, e.g. let BCN be a tourism whorehouse and improve the QOL in the suburbs, connect them with trains, shift big tech companies to relocate with tax benefits etc . It’s not a tourism problem its an everybody wants to be in the same city problem. Just expand what makes BCN amazing outwards . Transport , bike lanes , wide roads and urban planning . It’s like, they made one great plan and they forgot to iterate on it for the current time, and expand it properly. I don’t feel it’s fair to use capitalism as a sort of “swear word” freely . Like you state the problem can be attacked from a lot of angles and it’s not a “capitalism” problem but the sum of relations and norms , wants and needs. If all cities were “not capitalist” there would still be some more coveted than others and that would create a housing problem anyway.
