Why is it said that the underclass is trapped?

It is said that the underclass is trapped because numerous studies and surveys show that they are caught in a loop of social and economic problems.

Explanation:

When it comes to the distribution of resources amongst the people, the population that belongs to the underclass is seen to be incapable of fetching the resources towards them. This is because the underclass lacks the means of getting access to these resources. The problems faced by the underclass are way more intense and severe than the problems faced by the upper class. Low employability, poor health, addictions and other unhealthy habits, etc. factors have made it difficult for the underclass get themselves out of this loop.
