I think you are right. Ther are not enough quality tradesman. This should be great for those who are in those ocupations as there trade becomes more valued. If you pick up the book The World is Flat you see that there is no way to outsource this type of skilled profession. But you seem to have a very negative impression of education. Me thinks you have envy for those who do have a degree.
Using cash to pay for an education when the government is going to write the check is foolish. Three years ago you could ahve borrowed money through the Stafford loan program at 2.77 % and turned around and fixed the rate for 2.875. With differnt lender incentives the rates got down to 1.625% Paying cash would have been foolish. Get a clue before you make such a ridiculous statement that one should take up a trade if they don’t have the cash.
