From Mises’s Bureaucracy (1944),
On p. 79,
Most people joined the staff of the government offices because the salary and the pension offered were higher than what they could expect to earn in other occupations. They did not renounce anything in serving the government. Civil service was for them the most profitable job they could find.
On p. 81,
Representative democracy cannot subsist if a great part of the voters are on the government pay roll. If the members of parliament no longer consider themselves mandatories of the taxpayers but deputies of those receiving salaries, wages, subsidies, doles, and other benefits from the treasury, democracy is done for.
