> The purpose of tax advantaged retirement accounts is to reduce the number of destitute people in retirement. It achieves this goal by providing a tax incentive on regular investment for people who would not otherwise invest.

The purpose of tax advantage retirement accounts when originally introduced by ERISA was to give employees of private companies a safety net in cases where their pension defaulted or when a pension wasn't offered in the first place. There's really no mention of it being specifically for people who are destitute or would not otherwise invest. Traditional IRAs are available for everyone, even high earners, no gatekeeping.

Traditional IRAs are taxed on withdrawal and function much like other investments.
