car and computer industry

[kf10]

when i was in college our economy (year 1993) teacher told us that car industry is the world biggest industry, because it involves one in ten person worldwide directly or indirectly

can we say same thing about computer industry that it involves the whole world population directly or in directly

Although a greater than one in ten people in the world may use computers, either in their work or leisure, the number of people who actually make their living from the computing industries is likely to be far less than this - It could be argued, using a similar premise, that at the time of your original quote, and even more so now, the TV business is the worlds largest as the TV is so prominent in all our lives.
