The main question is whether tax savings are more valuable now or later.
Why younger workers often lean Roth
Earlier-career earnings can be lower than later-career earnings, which means paying tax now may be less painful than paying tax on larger future withdrawals.
Why traditional still matters
Traditional contributions reduce current taxable income, which can help if you are managing tight cash flow, high tax burden, or other priorities right now.
Bottom line
Roth often appeals to younger workers, but the better answer depends on current tax pressure and expected future income.
