eli5: Why isn’t carbon capture used at emission sources?

Question

I know that there is ‘legacy carbon’ in the atmosphere that needs to get removed but why aren’t we leveraging carbon capture as part of industrial processes (e.g. at the factory’s smoke stack, for example). Or maybe we are already?

Answer 1

Because polluters aren’t held accountable for their own externalities, so they pollute with reckless abandon, maximizing profits at everyone else’s expense.
