Earlier quoted context omitted.
US automotive lemon law for example doesn’t specifically benefit the wealthy or large corporations. What muddles the picture is people do benefit from economies of scale. So, if you make the law actually hostile for large companies both the general public and corporations are worse off.
Lemon laws only apply to cars sold with warranties. Wealthier people are more likely to buy new cars, or used cars with warranties. Poor people are relatively much more likely to buy cheaper used cars without warranties. Rich people also buy more cars over their lives, increasing their chances of coming across a lemon. Therefore, lemon laws are relatively more beneficial for wealthier people.
Thus lemon law benefits every single consumer whether buying a new or used car.
