I would disagree, this is not true for most places I have been to. Burqas are on a steep decline, and one common demand of Muslim women while marrying, is that the husband doesn't force them to wear a burqa. Some rare rich people who live in ghettos do wear one, but anyone living in mixed areas and actually interacting with other communities would not want to wear one. You will be judged daily.
(hyper religiosity makes you unwanted in most societies. That's a reason you will rarely see any Hindu wearing saffron or applying Tilak, in cities.)
For a working person, you are unlikely to be considered for most private jobs if you wear your faith on your sleeve.
They look poor. Poor households tend to be more religious.
