The Fed prints money, which it lends to the government at essentially zero interest rates. The money flows into the economy, largely to government, friends of government (e.g., Solyndra) and banks. There is a limit to how much stuff these folks need, so instead of buying stuff, they buy assets, including real estate and stocks, bidding up the price of both, and making them and their friends look richer. Bidding up real estate increases rents, making renters poorer.
Artificially increasing the difficulty of hiring people (through Obamacare and other regulations) increases unemployment, reducing the bargaining power of prospective employees. Etc.
Sorry but your response is way to simplistic. If the rich are driving up stocks then those who own them see their own holdings increase. If rents are increasing it is because many more people are renting rather than buying.
