It stopped being a free market system a long time ago. Sherman Antitrust is a problem, not a solution,
Where are the federal laws protecting consumers from unfair and rapines taxes by the insatiable Dems?
In the big picture, constraining government is probably far more important than preventing monopoly power.
These laws are all a bunch of B.S. The government is almost always at the bottom of a cartel that survives for an extended time - gov’t briberies and kickbacks and subsides to and from their favorite companies. The voluntary cooperation between buyers and sellers in the marketplace free from government interference will weed out the bad guys sooner or later.
Government price fixing always leads to disaster.
Antitrust law is a dead letter in America. The American economy has completely been cartelized and nothing was done to prevent it.

"The Sherman Antitrust Act is the first in a line of federal laws protecting consumers from unfair prices"
That only works if you don't regard the Constitution as "federal laws" because the Commerce Clause predates Sherman. SCOTUS used it in 1924's Gibbons v Ogden to break up the monopoly the State of NY had granted to the Fulton Steamboat company.
