<p>If an engineer is ethical, the building is far more likely to be well built than if it's built by a person who is unethical and cuts corners and lies about other unsafe things.</p>
<p>If a person plagiarized and otherwise cheated to get their engineering degree, they would not have the skills to build things as well as someone who fairly earned their degree.</p>
<p>If a person lies when it's convenient to themselves, I would not trust them to build a safe structure because it would be far more convenient to lie and increase their profits.</p>
