The United States should continue running on capitalism
America is not strictly capitalist.

Corporate execs should be prosecuted like other criminals if their deliberate decisions result in the harm or death of others
This posited statement needs to be fleshed out. Corporate leaders may have well projected information that some giant project or newly marketed item may result in some limited number of deaths. Large construction project, new drug. But the benefit for everyone else makes those losses acceptable.
