.............."Almost all of these industries provide services rather than products, which keeps their overhead costs low, protects profit margins, and tends to be more recession-resistant. (And in some cases, this business model also leads to higher than normal cash balances.) "
This was due to the fact that these industries were providing services rather than more tangible products, thus keeping overheads low and "need-to-have"- or you could end up dead.
Is that why healthcare is such a prized asset for businesses, and why they are desperate to crack open health sectors globally ?
