Generally speaking, in the US, contracts with minor (< 18) are voidable, that is, at any time the minor can break the contract. This creates a situation where no one would ever contract with a minor, which is obviously bad (how is an emancipated minor supposed to rent an apartment?) so there are statutory exceptions where the contract will be enforced.
Why would anybody rent to a minor otherwise, regardless of the contract breaking issues. They are unlikely to have much credit history. To say nothing of the maturity / responsibility and income (+ wealth / cash savings) problems.
The whole point of emancipating a minor is to empower them with legal decision-making power, in particular the ability to earn and retain wages.
Furthermore it's really hard to interpret your sentence with a meaning other than 'poor people do not deserve housing,' which I have to assume is not your intent.
