America's present strong dollar is just one more sign that our economy is the strongest on earth and that the U. S. is an attractive place to invest, financial observers say.

• Since the spring of 1995, the dollar has surged 50 percent against the Japanese yen and 20 percent against the German mark.

• While this may disadvantage U. S. automakers seeking to sell their vehicles overseas, it has been a boon to American high-tech companies as the cost of their foreign-made parts has gone down.

• Investors in other parts of the world find dollar-based assets a bargain and capital is being attracted from many countries by our high real interest rates.

• Other beneficiaries are American tourists and business people traveling abroad -- who find exchange rates advantageous to their wallets.
