Why do politicians put their own names on plaques?

When politicians put there own names on plaques like this, it demonstrates the hubris(extreme arrogance) of the State.

Politicians cast a vote to use force to extract(steal) wealth from property owners. These property owners have committed no fault except purchasing property within the geographical boundaries that these politicians claim to rule over(such as their city or county). The politicians then use the threat of violence to collect the money to build the park from these unfortunate property owners. If the property owner refuses to bow to the edict(command) of the politician, the politicians send the thug enforcers they call Sheriffs to forcibly remove the property owner from his home. The these mafioso(gang)-like enforcers called sheriffs auction the property off to collect the extortion money(money collect by threatening violence against a person) from the property owner. 

Of course, this threat of violence is understood by all the property owners, and since the mafia(gang)-like organization of politicians has many guns and obedient thug enforcers, most property owners willingly, if grudgingly, pay these extortion demands called taxes to avoid the violence. 

And when it’s all done, the politicians have the audacity(courage)

to put their own names in the plaque, as if their contribution to building the park was anything more than the threat of violence against their friends, family, and neighbors.
