Wow.. its clear to me that you've never actually gone through the legal immigration process. It is much worse than you paint it out to be. At best, you'll get treating with disrespect, dismisive attitude, rudeness, made to wait entire days in line, etc.. I speak from experience as a US citizen who had to get a visa for his wife.
My wife, father-in-law, mother-in-law, and sister-in-law went through the legal immigration process and none of them felt that they were ill-treated. Yes, the wait is long, but every bureaucracy involves waiting. You got a bad draw I guess.
Back in my day, we bootlegged our music on a 56k modem, and we were damn happy to have it!
Luxury. We used to tape record songs from the radio using hand me down portal tape recorders. If the DJ spoke to early or someone made a noise, the song was ruined!
...a diamond tipped cutter for cheese.
That may be handy for a block of 25 year old Parmigiano-Reggiano. Then again, I already have a chain saw, so I might try that instead.
Even if their was a 25% failure rate (which is obscene and not within the realm of feasibility) I guarantee that you'd have volunteers lined up to man the missions.
Would you be willing to take a commercial air flight if the failure rate was 25%? 15%? 5%? How many pilots would fly with those failure rates? How many companies would send expensive cargoes with those failure rates?
Hell - if things go right they'll be lining colonists up at the gate in the next few decades - and I'll be in line even if I only had a 75% chance of surviving.
Yes, they'll have a lot of volunteers, but how many of those volunteers will have the necessary physical capabilities and specialized skills? Those that do will be too valuable to risk unnecessarily. Besides, where can we put a colony? There simply isn't anyplace that compelling.
When you don't know what to do, walk fast and look worried.
