Some of the stuff on this thread is judging the religion, not the wealth, which I'm sure none of you mean to do, so I'll clarify a few things.
Hindu weddings do go on for days, a one day event is very alien to me.
The bride and groom would not have had control of their guest list, it's more than a wedding, it's a business event in this case. Even if you aren't a big business family, the first wedding in a generation for example is often used to bring the community together or reciprocate wedding invitations you've had (this could go back 20 years or more!). It's about togetherness of more than just the couple.
Although the wealth for these events has trickled down, I do struggle with the rich/poor disparity in these areas.
However, MN and the UK in general don't like it when other people become too successful, even if they're self made. I've asked numerous times on here what figure you're allowed to make before being vilified on here but no one has been answer me yet.
I'd also agree with PP that the colonial mindset is strong. I'd read up a little more of the impact of British rule on various colonies before you begin to comment.
