As White House economic reopening guidance expired on Thursday after two weeks in place, half of all U.S. states forged ahead with easing restrictions on restaurants, retail and other businesses in hopes of reviving coronavirus-stricken commerce. The enormous pressure on states to reopen, despite a lack of wide-scale virus testing and other precautions urged by health experts, was highlighted in new Labor Department data showing some 30 million Americans seeking unemployment benefits since March 21. The jobless toll amounts to more than 18.4% of the U.S. working-age population, a level not seen since the Great Depression of the 1930s.
