Explainers & guides.
One question per page, answered short first, then the numbers and the sources. Economics, Rust, iOS, AI and the things we learned the hard way building this studio.

Explainer · Economics · Oct 23, 2026What happened to banks after 2008?
Dodd-Frank tightened the rules in 2010, one Wall Street executive went to jail, a 2018 law loosened them, and SVB failed in 2023. The record, dated and sourced.
Explainer · Economics · Oct 23, 2026Did the government take money from Social Security and not pay it back?
No record shows the military took trillions. Surpluses were lent to the Treasury for interest-bearing bonds now being repaid. What is true, and the 2032 cliff.
Explainer · Economics · Oct 23, 2026What percent of federal income tax does the bottom 50% pay?
The bottom 50% paid 3.3% of federal income tax ($70B) in 2023 on 12.3% of income, but more in payroll tax. What removing it would cost, from IRS data.
Explainer · Economics · Oct 23, 2026How do interest rates affect the national debt?
The average rate on US debt rose from 1.42% to 3.52% and net interest passed $1 trillion in FY2026, above defense. How rates set the bill, with Treasury data.
Explainer · Economics · Oct 23, 2026Does building more housing lower rent?
Yes: rents near big new buildings fall about 5 to 7%, and 100 new units free up about 70 cheaper homes. The studies, the Austin test and the numbers, sourced.
Explainer · Economics · Oct 23, 2026Can the president lower rent prices?
Not directly: rent is set by local supply, zoning is local, and 32 states ban rent control. What Washington can do (vouchers, tax credits, mortgages), sourced.
