Yup, I pretty must agree with those responding to the OP. In summary, for starting, you are looking at at best 4k if coming from a local uni, at a slight premium of 6k coming from global recognized ivies.

I'll add value to this thread by suggesting possible ways if you really want to fast track to five digit per month asap. You friend is a good example. These are the few ways I know, outside the super lucky ones selling insurances, property, etc.

1. Yup, the IB and MC jobs. But as mentioned, they take in global ivies with internship experiences with them.
2. Sales in oil brokerage. Spend a year or two learning the business, then generate sales.
3. Start out as research analyst in an asset management company, generate a few good ideas, be reward handsomely. It depends on the style of investing, but know it isn't easy. You're golden if you can predict price movements correctly more than 50% of the time.

I'm from an Ivey and I'm in path 3.
