If you look at the graph, Trump was spending a lot even before COVID. Biden also spent a lot, but he also didn't run on "I will reduce spending" and instead you had the best COVID recovery of all western countries.
Also the other candidate was Harris, not Biden. Not that it really matters anymore.
For the bold part: I mean yes, that's just how it was globally. You can sacrifice some old people (like e.g. Sweden did) or sacrifice part of your economy and some of your and your childrens wellbeing - there was a tradeoff, the rhetoric is right. The decision arguably wasn't, although I personally am happy to still have three living grandparents.
Example of spending under Trump below. Republicans: we want to pass $300BN Covid aid. Democrats: no spend 2 trillion or you are killing people. Now dishonest hacks today want to pretend is was all Trump. I could find dozens of articles lionizing Democrats for wanting higher and higher spend under Trump.

The Republican bill included more money for a popular small-business loan program, a scaled-back version of an expanded unemployment benefit, funding for schools and the U.S. Postal Service, and liability lawsuit protections for businesses, schools and health care providers.
Republicans knew the bill would fail, but Senate Majority Whip John Thune, R-S.D., told reporters that it was in part a strategic move to show the GOP had a unified position that "puts pressure on Democrats to come to the table and to make a deal."
Democratic leaders preemptively rejected the Senate GOP bill. "Don't be misled by thinking: 'Oh, well, a little bit is better than nothing.' No, it isn't," House Speaker Nancy Pelosi told MSNBC. "It's a missed opportunity to do what is right for the American people."
Thursday's failed vote could be the last official act of Congress on a coronavirus relief bill before Election Day. Negotiations between Congress and the White House have been deadlocked for weeks over the cost of the relief package. Democrats want at least $2 trillion, which the Trump administration rejects as unnecessary overreach.
