Spencer Look and Jack VanDerhei: The Assumptions That Can…

PodcastThe Long ViewSpencer LookOct 13

The speakers examine retirement security through the risks that planning models can miss, especially long-term care, uneven shortfall exposure, and uncertainty around future Social Security benefits. They discuss how plan access, participant behavior, savings defaults, and policy proposals may affect outcomes, while emphasizing that assumptions about longevity, caregiving, Medicaid, and annuity use need to reflect individual circumstances. Jack also argues that plan sponsors should test proposed changes against actual participant behavior and results.

Key Takeaways

Morningstar's status quo model puts 40% to 45% of the population at risk of retirement shortfalls, versus around 25% when long-term-care costs are excluded, with lower-income workers, single women, and Black and Hispanic households more exposed. The speakers say planners have underrated long-term care, and Spencer recommends scenario analysis because care needs and costs vary across people.

The proposed Retirement Savings for Americans Act would create a federal Thrift Savings-like plan and default workers without employer coverage into it, while state auto IRAs offer another route to coverage. The speakers also identify lower participation among lower-income workers as a reason to broaden access, while Jack argues that access should come before features such as contribution rates and employer contributions.

The speakers say consistent plan participation and saving can put people in good shape through compounding, but Jack cautions that access and automatic enrollment alone may not produce adequate income. He points to higher default deferrals, automatic escalation, and limits on leakage, while also noting that match incentives and managed-account features can affect contributions.

Jack says Social Security's trust fund is scheduled to be unable to pay full statutory benefits in October 2032; if the issue remains unresolved, the 2026 trustees report's stated default is a 22% reduction, though he stresses that the outcome and reform details are uncertain. He recommends stress-testing for possible benefit cuts and higher payroll taxes, and Morningstar simulations suggest only a very small share of 401(k) participants could save enough to offset a potential benefit reduction.

GEO-POLITICS

Plan Coverage — The proposed Retirement Savings for Americans Act would create a federal plan similar to the Thrift Savings Plan and automatically enroll workers without employer coverage. State auto IRAs offer another way for uncovered workers to join a retirement plan.

“A recent one was the Retirement Savings for Americans Act, which would introduce a federal Thrift Savings like plan into the industry, and workers who are not covered by an…”—

ECONOMY

Long-Term Care Risk — The speakers say retirement planners have underestimated long-term care as a risk to retirement plans. Morningstar's status quo model puts 40% to 45% of the population at risk of shortfalls, versus around 25% when long-term-care costs are excluded.

“And Spencer and Jack have both concluded that the retirement planning community has underrated long term care as a risk factor for people's retirement plans.”—

Uneven Shortfalls — Morningstar's model finds that lower-income workers, single women, and Black and Hispanic households are more likely to face retirement income shortfalls. Its status quo estimate puts 40% to 45% of the population at risk, with the burden concentrated among some groups.

“We do think there are very clearly groups of people who our model is showing are underprepared, you know, higher rates of retirement income inadequacy. So there is a concentration…”—

Consistent Saving — According to the speakers, people who consistently participate in a retirement plan and save over time tend to be in good shape. They cite compounding and setting money aside as helpful.

“The people who follow those paths tend to be in pretty good shape…”—

Retirement Research Center

The hosts introduce Morningstar's retirement research center, which uses empirical analysis to help policymakers and plan sponsors assess policy, regulation, and plan-design trade-offs.

Retirement Outcomes Model

The guests describe a household-level microsimulation that incorporates changing work, savings, Social Security, longevity, and long-term-care patterns to estimate retirement income shortfalls.

Retirement Shortfall Risks

Their estimates put roughly 40% to 45% of Americans at risk of retirement shortfalls, with elevated risks for lower-income households and several demographic groups; regular plan saving improves prospects.

Social Security Reform

Jack argues that retirement-plan access and actual participant behavior matter alongside markets, while Social Security reform should be evaluated for solvency and its effects on household retirement adequacy.

Automatic Enrollment Design

The guests favor expanding access but caution that enrollment alone is insufficient without adequate default contributions, escalation, protections against leakage, and ways to bring workers back into plans.

Plan Design Effects

Small plan changes can compound into meaningful long-term differences, but sponsors should examine participant-level responses and effects on at-risk groups rather than rely on average estimates.

Small Employer Access

Federal and state proposals could extend coverage to workers without employer plans, while improved scale may help smaller employers offer more effective plan designs.

Retirement Spending Strategies

Retirement spending requires adaptation to uncertain lifespan, markets, and care needs; annuities and pooled-income approaches may help some people, depending on their circumstances.

Long-Term Care Planning

The guests recommend scenario testing for care needs, costs, family support, and Medicaid, arguing that models that omit long-term care can understate retirement shortfall risk.

Longevity and Plan Research

Because life expectancy depends on health, income, and other personal factors, advisors should test multiple assumptions; Jack also highlights new data linking plan design to employee behavior.

Upcoming Retirement Studies

The center plans further work on retirement-plan access, long-term-care insurance, lifetime income, and plan design, followed by the hosts’ thanks and standard disclosures.
