If you do have very specific goals in mind during your stay in college, $100K isn't going to sway you away anyway. Otherwise, it is probably a blessing to realize that there are other options available to you. Too many end up going to college simply because they do not see any other options or believe it is the only path to success and that is what Thiel is against.
If Thiel were to have children that decided to go to college, I am sure he would support their endeavours. It would not go against his worldview as long as they attended for the right reasons.
