I think young people should worry about a balanced budget since we are 18-19 trillion dollars in debt.
Tax Rates-The Boomers were always kinda anti-tax. I don't think Gen X or Gen Y has a anti-tax streak.
First off, the debt is a long term problem and there are a lot of much more pressing issues we need to fix before we can tackle it properly. Second, my generation and younger (I'm a millennial or what ever buzz word is in flavor) have seen that problem made worse by tax cut after tax cut and an unwillingness to undo those tax cuts despite them obviously not working. We're not stupid. We want results as opposed to promises that some how some ideology will magically fix this not really pressing problem.
So yes, you're right about younger folks not having as much of an anti-tax streak. But wrong about us thinking the debt will be the end all of our view on things.
