In the U.S., the Democratic party is the party of government and fully embracing of progressivism. The Republican party’s message is muddled. They say they are for smaller government, more freedom, and constitutionally limited government, but they too crave control.
Politicians, government employees, political insiders crave control, certainty, and stability. You hear them talk about stability of financial markets, of job markets, of domestic social and global situations. When they complain about “market fundamentalism”, the break-up of the family, wealth disparities, etc. they are making a play for control over the lives of the citizenry.
With that in mind, view any issue from the perspective of politicians. Growing a government bureaucracy is one way of maintaining control. The people employed in government agencies hold jobs in the bureaucracy. They are voters as well, but they are just as self-interested in their job security, money, respect, social acceptance, celebrity, and public adoration as anyone else. You see, money is not the only form of recognition. So when anyone cites something other than money when they are recognized for some achievement, they are seeking recognition by other means — as I listed above. They may feel good about themselves for avoiding recognition via cash payment, but they, nonetheless, are still seeking something. They are not selfless.
