He's correct and not correct. First, 'Industrialisation' also implies a fairly capitalist attitude towards everything and ornamentation may be costly in that context. Second, labour used to be 'cheap and plentiful', or rather, power was so concentrated, that the people who built such buildings could 'afford' the ornamentation (or maybe compel their serf-like workers to do it). And they cared about it because 'class' was a different thing altogether way back when. Third, ornamentation in many areas is still very expensive. To ornament, a building of any size would require designers, workers, and a lot of time and many. 'Some' products could be ornamentalized, but others, far less so. Suppose you built an office building with nice domed interior, and you wanted to have it 'ornamented' like a Cathedral. I wager it would be expensive.
