Demand employers pay a living wage
The start of this would be raising the minimum wage and indexing it to inflation. When inflation is at 4%, minimum wage also rises 4%. The problem isn’t that minimum wage has always been too low; When it was introduced, a single person could afford to live modestly while supporting a spouse. The problem is that it takes a literal act of congress to change. Instead of requiring congress to act again every few years, just tie it directly to the average of several different inflation calculations, (so a single one can’t be gamed by a future administration to keep wages low). Make it so that the adjustment is automatic.
Also, while we’re at it, make it free to file your taxes online. Have the IRS send a “here’s what we think you owe, and how we calculated it. Let us know of any corrections” letter to every single person. They’ve already done the calculation, and know how much you owe. And that’s what many other countries to. The US tax system is only complicated because the tax filing software companies lobby congress to keep it convoluted. They want to force people into using the software.
