I get it, that's the story we're being fed and the one I don't believe, although I don't have a better explanation.
Do you know what "not fully staffed, not enough workers" really means?
1. Why factory cannot produce enough ?
workers cannot work because they are infested with covid
workers cannot travel to work because of lockdown
factories have to close because of covid cases in the factory
no electricity because of no coal. so the machines cannot run
2. why suddenly a huge demand for some products?
billions of people have to stay at home because of lockdown
suddenly many people cannot do anything except trading from home
suddenly many people buy handphones, computers, EV cars.
suddenly not enough chips.
3. why products are not available in the store / supermarket?
because of above
because at the port, port workers are sick from covid
suddenly not enough shipping containers
because of sudden demand, there is a traffic jam at the port
truck drivers are banned from transporting goods unless the goods are
very essential
4. Then why factory cannot produce more
- coal, gas, chips, shipping containers ....?
and the cycle continues and continues
