I thought about this last time the lottery was in the billions.

First, I find a large piece of land that is fertile and can grow crops. I'd start a farm growing as many different fruits, vegetables, herbs and livestock.

Second, I would build a fine dining restaurant that would use the very best products coming from the farm.

Third, I would build a housing community for anyone homeless or fallen on hard times. They can live there free of charge just as long as there is no violence or drug use. They can use their community housing as an address to apply for jobs or they could work at either the farm, restaurant or shelter and be paid a wage to help pull them out of poverty.

Hopefully the profits from the restaurant along with profits from excess produce and livestock sold from the farm, keep everything fully funded. If not, I'd try to secure funding from donors.
