Something else to consider that might further support your point is that another way firms "eat"/deal with artificial costs imposed upon them by government is to eliminate jobs, reduce hours of workers, eliminate full time positions, which also results in a reduction in benefits employers have to pay out, employ/deploy technology to replace workers when possible, reduce the rate of raises and bonuses handed out versus meaningless promotions, outsource jobs, etc where profit margins are razor thin but volume is used to create profits.
Along with reducing the quantity and quality of goods and services so as to not directly raise prices but still cut costs in a stealthy way. So that "Big Mac" won't be as "Big" in comparison to what you could get in the past for the same price. All of these methods and more would be enacted before actual direct price hikes occur. Especially in price sensitive industries which depend on volume sales to make up for razor thin profit margins.
