More vulnerable populations are, without a doubt, having problems attaining items. However, this is not caused by other people stockpiling but it is a result of the hard-hit economic times. Most people who cannot secure things are generally living in poverty and they do not have a lot of savings. The beginning of the lockdown period led to many companies eliminating jobs and minimum wage workers were highly impacted. In America alone, 20.6 million people lost their jobs. 
As supermarkets began to gouge their prices, it became increasingly hard for vulnerable people to obtain items. This problem could have been slightly alleviated if the stockpiling frenzy had not occurred; but it would not have eliminated it.
