I agree and disagree. As a vocational educator I have seen the ebb and flow, or the ups and downs of the trades and how it is linked to the economy. When one sector takes a hit other sectors may do better. I have seen auto technicians do well when the economy is down because people hold on to their old cars longer. I have seen electricians and carpenters get laid off when the economy is down because lack of investment in new construction. I have seen home improvement people do well when the economy is down because people improve instead of buying a new home. Plumbers- don't ask me why but they always seem to do well! A lot of money in $#!+. Nurses too! The list of examples could go on............ The vo-tech I work at (23 years) graduates everyone from carpenters to cooks, welders to machinists, nurses, dental assistants, electronic technicians, auto technicians, HVAC people, etc. We have over 40 programs and every one of them has had its ups and downs through the years. On the other hand many of my friends (college grads) have had their share of layoffs, middle management squeeze outs, job losses due to mergers and acquisitions, and of course economic crashes. How did all those bankers, mortgage brokers, stock brokers, etc. do during the last big crash? The last time I did my taxes with an accountant he was moving into an office with half the space because turbo tax killed his business. There are just as many white collar examples of ups and downs as there are blue collar. I think every job- blue collar, white collar, college required or not has ups and downs. One thing for certain- anyone who keeps themselves up to date and marketable can usually survive the ups and downs. 40 year careers doing the same exact thing are mostly a thing of the past. Stay ahead of the curve and you will usually survive.
