I don’t think only investing into business and production is what would help. If those businesses get taken over by venture capitalists or go into stocks, then the motive shifts towards profit, rather than people.

It’d help more if those businesses were worker co-operatives, and their people worked together to establish community exchanges, and the workers use the profits of cooperatives to:

1. save for crises, ensuring that even then, workers still can thrive.
2. establish more businesses in different sectors, being all horizontally federated.
3. grow funds to outcompete capitalist structures, to take them over and turn them into other worker-owned cooperatives, and so the ball keeps on rolling.
4. train themselves to defend one another, and learn each other’s jobs. This in case scabs (strike-breakers) or cops arrive and arrest some workers.

Especially farms, mines, woodlands, – anything involving natural resources and land – would be crucial.

Sure, in this age of digitalisation, a lot happens online, too. But even then, at its root, for data centres you need land, water, and resources. For computers, you need minerals, from mines. For cables, you need boats of hardy materials. And for those labourers, you need farms and woodlands to supply them and their clothing.
