My hope is that it wouldn't be as bad as one might think. Dense living arrangements are more profitable for cities and local businesses and can allow cities to focus on infrastructure improvement and welfare. A problem with the megabuildings could be if they are solely owned by megacorps, but hopefully people will start looking into housing cooperatives to reduce costs and put more power in the hands of tenants. It doesn't have to be like we only build skyscrapers either, but imo we need to have more of a gradient in terms of building height depending on distance to the city center; different apartment building heights have their own benefits. This is just my dream, though.
