‘A system that counteracts those selfish tendencies’ you mean a system in which:
- housing is not controlled by companies with no moral incentive to keep them liveable and affordable?
- people don’t learn from a young age that their value is directly connected to their willingness to fuck people over for money?
- there is no monetary incentive to create artificial deficits in essential goods like housing and food?
- the whole economy is not based on ‘cheap labour’ and the illegal extraction of minerals from other countries?
More working class children means that there will be more people to exploit in the future. The size of the working class population is extremely important for the generation of wealth because they’re basically the only ones doing productive labour.
