A month ago, when an initial gauge of first-quarter economic growth came in surprisingly weak, many policy makers and economists expected the bad news to prove fleeting. But when revised data were released last week, the growth estimate remained stuck at an annual rate of 1.8 percent, compared with 3.1 percent at the end of last year.

More troubling in the latest figures, consumer spending — the largest component of the economy — was especially slow. Stagnant wages and higher prices for gas and food are squeezing family budgets, while falling home equity hurts consumer confidence. That suggests more bad news to come.

When consumers are constrained, so is hiring, because without customers, employers are hard pressed to retain workers or make new hires. A recent Labor Department report showed a greater-than-expected rise in the number of people claiming jobless benefits even as private-sector economic forecasts are being revised downward — both very bad omens for continued job growth.

Republican lawmakers have responded to renewed signs of weakness with a jobs plan that prescribes more of the same “fixes” that Republicans always recommend no matter the problem: mainly high-end tax cuts, deregulation, more domestic oil drilling and federal spending cuts.
