From a historical perspective, it would indeed seem implausible for a large population of slaves to be able to leave with significant quantities of valuable items, without intervention or opposition from their masters. However, it's important to note that the characterization of the Israelites as 'slaves' in the traditional sense, toiling en masse on the great building projects of Egypt, is also debated among scholars. The cultural, social, and economic nuances of ancient societies don't always translate neatly into modern terms.
