I briefly interned with a big Financial Services firm, they sold your usual Bonds, MFs, Equity and Insurance products.
They might carry you through some technical jargon but let me tell you this in most cases they are selling stuff that the Insurance Company's representative is pushing and the firm in the process gets paid a certain commission for every insurance/product you sell.
The firm where I worked basically also had various competitions among other branches, so say in a particular quarter whichever branch sells the most of a particular Mutual Fund NFO will get to travel abroad or something like that.
The issue here is ethics, if I'm incentivized with a foreign trip and all I've to do is sell insurance/MF then obviously I'll be overlooking the customers alignment with the policy.
Again I'm not implying your Uncle does that. But just so people here know that Agents usually have sales targets(SUPER SUPER STRICT TARGETS)/ major incentives pushing them hence they more often than not are not operating in your interest. Always try to take a second opinion.
