As a minor - and politically incorrect - historical aside, the term carpetbaggers was originally applied to unscrupulous Jewish traders who were "such an intolerable nuisance that the [South], must be purged of them".
Although the prejudices do not apply to all Sindis, or even all Bhaiband - the jati Lekhraj Kirpalani and the BKs emerged from, the term "carpetbaggers" would also apply very accurate to them and their advantageous adoption to British Empire and exploitation of it. Often an illicit exploitation, e.g. they employed Amil scribes who used secret private languages to evade tax and duty collecting agencies, as they spread across the influence of the Empire.
Sindis are often called "
the Jews of India", largely in the pejorative use of the term relating to their business, money making and materialistic tendencies. To the extent that, in the Gujarat, there is a saying, "If you meet a Sindi and a cobra on the road ... kill the Sindi first".
Funnily enough, as the BKs expanded, for the lack of sufficient numbers of Amils, the Sindis adopted largely submissive Gujarati "managers" as their assistants.
Obviously, the politically correct will rebel at such bold references, so please allow me to underline that they are not my prejudices ...
it's more recently been taken more positively, e.g. correlating both societies' rootlessness and diasporas ... however, I think to trully understand the Kirpalani Klan's backbone and soul, one needs to look at the community they came out of and its archetypal modes of operations.
For example, straightaway one sees why Lekhraj Kirpalani was loyal to the British and anti-Indian independence etc. But given that the first BKs centres were financed by Sindi merchant traders overseas, e.g. Janki Kirpalani piggybacking on Jayanti Kirpalani's Father's wealth in London, there are obvious connections. And more than just these.
The secrecy surrounding money, the passing of it around international networks the manner in which they established centres etc ... it all correlates very closely. In the accounts, BK UK passes back £500,000 to Mount Abu in one year to pay for dinner.
And they have the audacity to do so tax free as a "charity".
