Amtrak is owned by the federal government. The President appoints the board of directors. It’s literally socialist (public ownership of the capital stock).
Technically you vote for a capitalist oligarch to represent you, the peasant types like AOC are rare in elections. The only "socialism" here is socialism for the rich.
or rather, over-regulation, union focus on maximizing employment numbers instead of total compensation and quality of life, and similar short-term thinking (edited to reflect that I believe private sector unions are generally good, but focusing on membership count is not)
