When comparing space budget allocation, why is redirecting that sum insufficient to solve major Earth issues?

The space budget represents only a small fraction compared to the trillions needed for issues like global poverty or healthcare crises

While the moral imperative to solve persistent Earth problems like poverty or healthcare crises is paramount, comparing the scale of these massive systemic issues to the space budget reveals a critical disparity in financial needs. The funding dedicated to space exploration often amounts to less than one percent of discretionary spending. Redirecting this entire sum would provide only a negligible fraction of the trillions required to truly address and resolve deeply entrenched problems such as global poverty or worldwide healthcare crises. Furthermore, the political and economic decisions that drive these larger systemic issues are generally distinct and not directly linked to the decisions affecting the space budget, meaning the programs operate as separate, long-term investment streams.
