One industry can be booming while others aren't, because they aren't. It all stems from the shifting of priorities and money. It is the boom and bust cycles that everyone should eventually see as a constant with Capitalism. Money is removed from a specific industry during boom times and paid out to investers (the wealthy, predominantly) instead of being banked in order to allow the industry to better weather the bust times. The non-wealthy eat the losses through cuts and other scale-backs within the industry while the wealthy are not and are taking more money from them in another industry's boom time. So, while you may be doing well now, know that your time will come again when your industry cycles back to bust unless you are among the few that make money through money and not real work.
