Actually people are very prepared for that. In the US for example, the US collected a waste fee for 50 years and had many, many billions on an account. Easily enough money to develop the technology for burning up the fuel. Literally many times the money then required. But rather then using rational technology solution politicians grid-locked themselves over an incredibly stupid Yucca Mountain project that makes no sense what so ever. So yes, nuclear 'waste' needs to be managed, but there are well known technology solution. Sadly because people were anti-nuclear politicians rather sold the 'put it into a deep hole' story rather then developing the necessary technology.
