That will alway be the case if the power resides in the people. Areas with more people will have more power.
With gerrymandering they are fucking with that premise by creating artificial population divides to create political power, usually by the party in power to benefit their own party.
Counties could be split into districts or all representatives elected at large.
But if the voting districts were restricted to within counties, it would limit their ability to grab power from the people. Counties with larger populations would of course have more representatives, hence more power, as it should be.
