Managers’ interests can be aligned with the long term interests of the firm by giving them non-voting preferred shares as part of their compensation.
It really depends on the specific form of socialism. If we look at the most influential forms (say, USSR or China), the decision makers are politicians, so they’re more motivated by power and influence than the good of the whole.
IMO, socialism can work if it’s practiced by smaller orgs and not as a government structure. So unions and co-ops, not planned economies.
I’m not a socialist because I think markets are useful and haven’t seen a planned economy proposal that seemed plausible. Worker co-ops and unions aren’t socialism in 20th century sense because they are technically compatible with markets and private property.
An economic democracy is a market economy where all firms are worker co-ops, so I was speaking about managers in a worker co-op
