Identifying groups of people that could be customers but aren't because of some external factor and figuring out if you can do something to mitigate that factor

Identifying groups of people that could be customers but aren't because of some external factor and figuring out if you can do something to mitigate that factor is a perfectly normal part of business. A company doing that isn't trying to solve the underlying issue. That is indeed, as you noted, probably something they cannot do and others are better equipped to handle it. For instance suppose you find out that many women with young children are not coming to your business because they have no one to look after the kids while the mother is there. You might add a supervised playroom so the mothers can bring the kids and leave them in the playroom. This doesn't come anywhere near solving the underlying issue of daycare being too expensive for many parents but it could increase your business and make the lives of those mothers tangibly better.
