First, your statement that "no one" has figured out how to do "free health care" is false. ALL developed nations have, with the lone exception of the US--- though Obamacare has taken us closer, much closer. 
You have challenges in finding workers---- but you did find them, didn't you? Perhaps something is wrong with your wage structure: pay more. 
Your competitors also face the same challenges: the impact won't be on your business, alone. Higher wages mean more money for workers to spend-- at your business.
In a nation where the largest employer is a warehousing chain (Walmart) and the other huge similar businesses employ massive numbers of workers, I'm sorry to tell you that a living wage is a necessity. 
You say you're not wealthy--- but that's a comparative term. How much does your paycheck work out to, per hour? 
On a personal note, you should take a long look in the mirror and ask yourself how much the well-being of your neighbors means to you--- or if they're just so many robots.
