Learn Finnish: Varallisuuden takia niukkuudessa ei enää eletä. - Because of wealth, one does not live in scarcity anymore.

In Finnish, the passive is not just for actions done to an object. You can passivize intransitive verbs to express a generic state or an action done by an unspecified group of people. Here, the passive implies that people in general, or society, do not live in scarcity.

Why is the verb form eletä instead of the standard passive eletään?

Because this is a negative sentence. The affirmative passive form is eletään. When you make a passive sentence negative, you use the negative verb ei and drop the personal ending from the passive verb, leaving the connegative form eletä.

Why is the state niukkuudessa (in scarcity) placed before the verb?

Passive sentences lack a grammatical subject. To anchor the sentence and create a natural flow, Finnish often moves a location, time, or state to the position right before the verb. Starting with the verb ei eletä would sound abrupt here.

Why is varallisuus (wealth) in the genitive case (varallisuuden)?

It is required by the postposition takia (because of). In Finnish, words that come immediately before a postposition almost always need to be in the genitive case.
