Rhetorical Strategies in Healthcare Argument

In the following excerpt from a persuasive essay addressing the need for universal healthcare, the author employs several rhetorical strategies to enhance their argument:

"Imagine a world where no parent has to choose between paying for groceries or providing necessary medical care for their child. Every day, countless families face this unimaginable choice. Universal healthcare is not just a dream; it is a moral obligation we owe to one another as members of a compassionate society. By prioritizing health for all, we not only save lives but also foster a stronger, more productive community. Now is the time to embrace this change and recognize that healthcare is a fundamental right, not a privilege reserved for a select few."
