Stop asking loaded, emotional questions. If you really want to learn something, ask it in good faith.
The answer is that you stop STEALING people's productivity and encourage them instead to SAVE THEIR MONEY.
The whole economy is based on CONSUMING. Every tax, every index, every measure of 'growth' and 'economic fortune' is based on CONSUMPTION.
Go back and learn Austrian economics and stop stealing from people with the inheritance tax and corporate taxes and gas taxes and air taxes and high energy costs and the income tax. Stop spending incomprehensible sums of money on nonsense, racking up enormous national debts which crush the middle class. Knock down the walls of state lines health insurance and give people choices so the middle class will not be crushed by insurance premiums. Stop rewarding congress with insider trading deals. Teach dollar cost averaging.
And finally, to answer your angry, petulant, emo question about SS - grandfather in all current recipients and those within 10 years. Everybody else has time to start saving but the government HAS to get out of the way.
