Has the legal system change recently to eliminate lawsuits?

No, the system has not changed recently to limit lawsuits. A few courts have significantly raised their filing fees lately, but this is generally for the purpose of raising funds, not reducing suits.

Some rules of procedure are in place to allow courts to quickly dispose of frivolous suits or suits that have no hope of winning, but these have been in place for a number of years.

Some states are starting to introduce legislation known as "tort reform." This legislation is meant to cap awards for negligence and malpractice claims. However, this does not eliminate lawsuits, it simply limits the ones that exist.
