The tragedy of being refugees was shared by over 100 million people during and after the second world war, when empires collapsed and new world order has been formed. None of those refugees have kept their status, and they integrated within the countries they were deported to. None, except the palestinians, who were less than .6% of the then refugees. The difference is that the arab states, the palestinian's hosts, would not accept the outcome of the failed war which they asserted in 1948, and maintained the refugee status to all palestinians, limiting their movement and denying them basic civil rights. Meanwhile, about the same number of jews left the same arab countries and migrated to Israel.

In India and Pakistan, where massive populations were displaced, following their independance, there are no refugee camps anymore. The same goes to Germany, Poland, Ukraine, Russia, South Korea, and many many more.

One cannot undo history, nor can the palestinians deny the sad fact that they should consider other options, rather than to pray - and act - to annihilate Israel. So far, this was the only mode they operated.
