Completely agree. While there are a lot of startups that may not be tackling "meaningful" problems, there are plenty that are. On top of the ones you mentioned there are many FinTech companies that are focused on helping middle and lower class Americans.

The Financial Solutions Lab has tons of startups interested in tackling large financial problems. Even works on income smoothing to make hourly and seasonal workers have steady paychecks. Digit helps with automated saving. Tala uses machine learning to create credit scores for people in Kenya, Tanzania, and other developing countries. Nova Credit helps immigrant gain better credit. There are dozens more that are all helping people get access to better/fairer financial products.
