Debt is one of the biggest daily concerns for 68% of millennials, according to a new poll by Hometap, and they are seven times more likely than people over 50 to say that paying credit card or student debt is an important financial goal.

Why it matters: A majority of millennials say baby boomers have made things worse for them, according to an Axios/Survey Monkey poll, as they struggle with big college loans, inheriting two wars, and facing an uncertain future of work. But only 56% of them said they are "extremely" or "very" responsible in how they manage their money, compared with 80% of those 70 years old and more.

More than 50% of millennials' salaries go to mortgage payments, according to the Hometap poll. And 70% say that high mortgage payments make it harder to reach their financial goals.

They are 30% less likely than those 50+ to believe they will ever receive social security.

Be smart: 85% of millennials are personally saving for retirement.
