Lawyers just ask courts to enforce the law. If you didn’t have that, people would take matters into their own hands with a lot of vigilante justice and you know who would win that world - the people with money who can afford the vigilantes. Big money may win at lower levels of court, but they don’t win the higher you appeal.
This world would suck without lawyers. Usually, the folks I’ve run into who complain about lawyers actually just don’t like the laws…blame the legislature…not the lawyers.
