Never said they stopped: industry 'leaders', authoritarians, will always try to keep and expand their abusive grip over others and claw as much power from the common people as possible. The methods are always the same: distraction, disinformation, abuse. The common people's only defense is transparent institutions and limiting power/wealth in general.
See also how the robber barons of the 1930s (Rockefeller, JP Morgan, etc) already tried to overthrow the government to establish a fascist military dictatorship.
The democrats participate in this export strongly too. Biden shut down a really important union strike. They are less overt about it, but go watch Malcolm X talk about foxes and wolves.
