FLINT , Michigan ( CNN ) -- Sen. Barack Obama Monday proposed spending billions to revitalize the nation 's economy , a plan the campaign of his likely Republican opponent said would slow economic growth with higher taxes . Sen. Barack Obama wants to spend $ 60 billion on America 's infrastructure . During an economic speech in Flint , Michigan , Obama promised to spend billions to improve America 's education , infrastructure , energy and health care systems . To improve America 's competitiveness , the senator from Illinois said he wants to spend $ 10 billion on childhood education , $ 150 billion over 10 years on developing alternative energy and $ 60 billion over 10 years to build `` 21st century infrastructure . '' Obama said he would pay for these programs by ending the war in Iraq , reducing government waste , charging polluters for greenhouse gas emissions and ending the Bush tax cuts for wealthy individuals . During his speech in Michigan , a state hard hit by the decline of the American automobile industry , Obama also rejected protectionist trade polices that many unions say would help protect American jobs , saying `` it is impossible to turn back the tide of globalization . '' Watch Obama call for America to compete in the global economy » . Obama said he disagreed with those who want to `` build a fortress around America ; to stop trading with other countries , shut down immigration , and rely on old industries . '' `` Not only is it impossible to turn back the tide of globalization , but efforts to do so can make us worse off , '' Obama said . `` Rather than fear the future , we must embrace it . I have no doubt that America can compete -- and succeed -- in the 21st century . '' A McCain spokesman attacked Obama 's plan , saying the Democrat 's `` agenda to raise taxes and isolate America from foreign markets will not get our economy back on track or create new jobs . '' `` To help create jobs in America , we need to lower taxes and open up foreign markets to American goods , '' said McCain spokesman Tucker Bounds . `` Americans can not afford Barack Obama 's 'change ' that takes us back to the failed policies of the past . '' But Obama said now was the time to commit to long-term investments in America 's future and blasted McCain for wanting to continue President Bush 's economic policies , saying `` there is a clear choice in this election . Instead of reaching for new horizons , George Bush has put us in a hole , and John McCain 's policies will keep us there . I want to take us in a new and better direction . `` I reject the belief that we should either shrink from the challenge of globalization or fall back on the same tired and failed approaches of the last eight years , '' he said . `` It 's time for new policies that create the jobs and opportunities of the future -- a competitiveness agenda built upon education and energy , innovation and infrastructure , fair trade and reform . '' The two campaigns have been sparring over who would be a better steward of America 's ailing economy , and both candidates have been reaching out to blue-collar voters , many of whom backed Republican President Ronald Reagan over the Democrats , in part , because of cultural issues . `` I believe that there are stark differences between myself and Sen. Obama . ... And I believe that the same appeals that President Reagan made to the so-called Reagan Democrats will succeed there , '' McCain said during a campaign stop in Arlington , Virginia . Watch McCain vow to win Reagan Democrats » . A CNN/Opinion Research Corp. poll released Thursday suggested voters favor Obama over McCain to handle the economy 50 percent to 44 percent . The poll , conducted June 4-5 , had a margin of error of plus or minus 3 percentage points .
