WASHINGTON (Reuters) - President Joe Biden plans to unveil a sweeping $1.8 trillion package for families and education in his first speech to Congress on Wednesday and will argue that he has restored faith in democracy 100 days after he succeeded Donald Trump in office. The plan includes $1 trillion in spending on education and childcare over 10 years and $800 billion in tax credits aimed at middle- and low-income families, according to a White House fact sheet. There would be $200 billion for free, universal preschool for 3- and 4-year olds and $109 billion for free community college regardless of income for two years, the White House said. The spending plans “reinvest in the future of the American economy and American workers, and will help us out-compete China and other countries around the world,” it said. The American Families Plan and the infrastructure and jobs plan the White House introduced this month could represent the most significant government transformation of the economy in decades. “We have to prove democracy still works, that our government still works, and can deliver for the people,” Biden will say. “In our first 100 days together, we have acted to restore the people’s faith in our democracy to deliver.” Biden faces opposition to his agenda from Republicans who say he is spending too much and liberals who want him to take more aggressive steps. He addressed Republican opposition in a session with TV news anchors at the White House hours before the speech. “Everybody talks about, can I do anything bipartisan? Well, I got to figure out if there’s a party to deal with. We need a Republican Party. ... We need another party, whatever you call it, that’s unified - not completely splintered and fearful of one another,” Biden said, according to a tweet from CNN anchor Jake Tapper. The president is gambling that his spending plans, which are largely popular with American voters, can sway Republicans in Congress to cooperate with the White House. PROPOSED TAX OVERHAUL To pay for the plans, Biden has proposed an overhaul of the U.S. tax system. Wednesday’s “American Families Plan” is funded by raising the top marginal tax rate for the wealthiest Americans to 39.6% from its current 37%. It nearly doubles the tax on investment income – known as capital gains – for Americans who earn more than $1 million. The $2 trillion-plus infrastructure plan is funded by an increase in corporate taxes. News of the capital gains tax proposal briefly sank stock markets last week. The Biden administration says the tax reform plan is designed to reward work, not wealth, and “reform the tax code so that the wealthy have to play by the same rules as everyone else.” Biden will use his speech to signal openness to bipartisan compromise on policing, speaking positively about negotiations on a reform bill in Congress. Senator Tim Scott, the only Black Republican in the chamber, is set to give his party’s rebuttal to Biden’s speech, with police reform expected to be among the topics. Biden will also discuss foreign affairs, how his administration has handled the coronavirus pandemic and the status of vaccinations. One senior congressional aide said Biden was expected to “come out hard on China,” noting frequent calls to take a harder line against Beijing from both Republicans and Democrats. In his decades in elected office, Biden attended dozens of his predecessors’ joint addresses to Congress. The scene he faces when he takes the podium at the House of Representatives during a pandemic will look very different. Just 200 people, mostly lawmakers plus a handful of representatives of other branches of government and family members, will attend the masked, socially distanced speech. That is a far cry from the more than 1,000 officials, friends and guests who typically gather for such a presidential speech. The nationally televised address, however, targets an audience far beyond the reduced-sized crowd on Capitol Hill. About 48 million people watched Trump’s first address to a joint session in 2017. Republican Senator Mitch McConnell, the Senate minority leader, said ahead of the speech that Biden had not followed through on his promises of seeking unity and has tried to placate liberals instead. “Over a few short months, the Biden administration seems to have given up on selling actual unity in favor of catnip for their liberal base, covered with a hefty coat of false advertising,” McConnell said.
