It's probably not correct to say that it's more profitable to play a certain card range at any stake. I think it's more correct to say that it's EASIER to make a profit playing a very narrow and very strong range in live 1/2 - 5/10 games. The higher you go in stakes though, the more likely you are to run into very solid opponents who will pick up on your tendencies and attempt to exploit them. I don't mind playing at a table full of nits as I will win a lot of tiny pots and fold vs aggression a lot. Some may think it's slow and boring but I think it's safer and easier money. At a game full of LAGs you'll have much bigger pots and tougher decisions. Done well, nit and LAG ranges can both be profitable. The question is usually which style works best against your current line up and which style works best for you personally. In general you want to be doing the opposite of what everyone else is doing. So if the table is too tight you can adjust by loosening up and stealing a large number of small pots. If the table is too loose you can tighten up and win a small number of large pots.
