Education is largely a commercial enterprise nowadays aimed at securing increasingly high tuition fees while producing workers suited to commercial interests. This is why universities will often speak of who will hire you with what degree. The point of course is to 'get a good job', which really means you get a degree with the intent of boot licking a HR agent in order to then get a position which hopefully maximizes your consumption capacities. As a middle-class wage earner with access to much consumer goods and housing loans, you then gain appreciation from society and feel like you have 'made it'.
The baby boomer generation got to enjoy that lifestyle without too many obstacles compared to later generations.
For better or worse, with increasing energy costs and globalization, the rat race is getting that much more severe. First world economies are 'mature' which means they don't manufacture much stuff any longer because poor peasants in the third world will do it for a lot cheaper, and the lack of trade tariffs means it is only logical for manufacturing to go overseas. That leaves some amount of production, retail and service, though that has its limits. The economies of the western world are stagnating for various reasons. The older career and education model assumed there would be a need for increasing numbers of well-educated professionals, but this is clearly not the case any longer. Even if you are tradesperson, your business might fluctuate. Canada's economy as an exception is roaring, but that's largely due to tar sands and other resource extraction, all of which is morally reprehensible and moreover finite.
Younger generations don't have the foundation their parents did. The retirement age is increasing, pensions are getting slashed and various social securities are being pruned. This is the result of economies running out of steam. It won't get better. It will only get worse.http://ourfiniteworld.com/2013/11/15/wh ... tion-cost/
If you want to live as a renunciate, then you need to live a simple lifestyle. Have no more possessions than what fits into a backpack or two. This is how I operate, even before I put on the robes. It enables you to move freely and not worry about possessions. If you have furniture, appliances and excess clothes, then you have to worry about them and it makes mobility difficult. Mobility enables you to move to greener pastures wherever necessary. If you live with a bare minimum budget, then finances are less of a concern. You can save more money which can be used through hard times. Frugality is essential to survival.
Also get a valuable skill you can take anywhere with you. If you can be a general handyman, capable of doing basic electrical work and other such tasks, then you'll find it easy to secure a basic income. You could also provide something to monasteries if need be that is much needed. You could get room and board in return (I know one place where this is in fact the case).
